When a group data is involved, cumulative frequency is used. The formula will be: Median=[(N+1)/2]th

  For member of odd number items. That is, where N is odd

  Median=([N/2]th + [N/2 + 1]th)/2

  For member of odd number items. That is, where N is odd

  Solution:

  From the table, there are 20 members as indicated by the cumulative frequency. Since the members are odd (10) the median age will be ([N/2]th + [N/2 + 1]th)/2

  Median=([10/2]th + [10/2 + 1]th)/2

  =(5th + 6th)/2

  The 5th member is 3 and the 6th member is on 3

  Median=(3 + 3)/2

  =6/2

  Median = 3

To calculate the population density of Nigeria, we need to divide the total population of Nigeria by its total land area. So, Population density of Nigeria = Total population of Nigeria / Total land area of Nigeria Plugging in the values, we get: Population density of Nigeria = 180,000,000 / 923,768 sq km Solving this equation, we get: Population density of Nigeria = 195 people per sq km (rounded to the nearest whole number) Therefore, is the correct answer. Nigeria has a population density of approximately 195 people per square kilometer, which means that on average, there are 195 people living in every square kilometer of land in Nigeria. This number is relatively high compared to some other countries, but it is important to note that population density varies widely depending on factors such as geography, climate, and economic development.

Both statements are correct. Climate and availability of water are important factors that can affect where people choose to live. Areas with a favorable climate and a reliable source of water are often more attractive to people, leading to higher population densities in those regions. On the other hand, areas with harsh climates or limited access to water may have lower population densities. Density of population refers to the number of people living in a given area. By understanding the population density in different regions, we can get a better understanding of how densely populated an area is and how the population is distributed over the land. This information is useful in a variety of fields, including urban planning, resource management, and public health.

The basic economic problems of society refer to the fundamental challenges that arise from the limited availability of resources and the unlimited wants and needs of individuals and society as a whole. The three main economic problems are scarcity, choice, and opportunity cost. Scarcity refers to the limited availability of resources, such as land, labor, and capital, relative to the unlimited wants and needs of individuals and society. This means that choices must be made about what to produce, how to produce it, and for whom it should be produced. The second economic problem is choice. Because resources are scarce, individuals and societies must make choices about what goods and services to produce and consume. This requires answering questions like "what to produce," "how much to produce," "how to produce it," and "for whom to produce it." These choices have important consequences for the allocation of resources and the distribution of income and wealth. The third economic problem is opportunity cost. This refers to the cost of choosing one option over another, as measured by the value of the best alternative foregone. In other words, every time we make a choice, we give up the opportunity to do something else with those resources. This means that the cost of any choice is not only the direct cost of producing or consuming a good, but also the opportunity cost of not using those resources in some other way. In summary, the basic economic problems of society include scarcity, choice, and opportunity cost. These problems arise from the limited availability of resources relative to the unlimited wants and needs of individuals and society, and require making choices about what to produce, how to produce it, and for whom it should be produced.

The formation of cartels or monopolies in order to obtain better bargaining or deals from other countries is characteristic of countries producing the same or identical goods. When multiple countries produce the same or very similar goods, they may face competition from each other in the global marketplace. This competition can lead to lower prices and lower profits for all the countries involved. To avoid this, these countries may form a cartel or monopoly by agreeing to work together to limit production or fix prices. By doing so, they can increase their bargaining power and negotiate better deals with other countries or buyers. For example, the Organization of the Petroleum Exporting Countries (OPEC) is a cartel made up of oil-producing countries that work together to regulate the supply and price of oil in the global market. By working together, they can maintain higher prices for their oil and negotiate better deals with buyers. Overall, the formation of cartels or monopolies can be a way for countries producing similar goods to gain more control over the market and secure better economic outcomes for themselves.

The reward for land as a factor of production is rent. Rent is the payment made by a tenant or user of land to the owner of the land in exchange for the right to use the land. Land, as a factor of production, refers to the natural resources such as water, air, forests, minerals, and other resources that are used in the production process. Unlike labor and capital, land is considered to have a fixed supply, which means that its availability is limited. Therefore, the price of land is determined by the demand for it, which is influenced by factors such as location, natural resources, and economic activity. In summary, the reward for land is rent, which is the payment made by a tenant or user of land to the owner of the land in exchange for the right to use the land.

In the long run, all production factors are variable. This means that in the long run, a firm can adjust all of its inputs, including labor, capital, and resources, to produce the level of output it desires. Unlike the short run, where some production factors are fixed and cannot be changed, the long run allows firms to make changes to all of their inputs, such as investing in new technology or equipment, hiring or firing employees, and even moving to a new location. For example, in the short run, a bakery may only be able to increase its production by hiring more workers or working longer hours, as its oven and baking equipment are fixed. But in the long run, the bakery could invest in new, larger equipment to increase its production capacity, as well as relocate to a larger facility or even open new stores. Therefore, in the long run, all production factors can be adjusted, making them variable, while in the short run, some factors are fixed, making them less adaptable to changes in production levels.

To calculate the population density, we need to divide the total population by the land area. Population density = Total population / Land area In this case, the total population is 100 million and the land area is 50 square kilometers. So, Population density = 100 million / 50 square kilometers Simplifying the above expression, we get: Population density = 2 million people per square kilometer Therefore, the correct option is "2 million people per square kilometer".

The mean is considered the best measure of central tendency because it is a balancing point in an observation. Central tendency refers to the tendency of data to cluster around a particular value in a distribution. The three measures of central tendency are mean, median, and mode. The mean is the arithmetic average of a set of data and is calculated by summing all of the values and dividing by the number of values in the set. The mean is the balancing point in an observation because it takes into account all the values in a set of data and calculates their average. It is the sum of all the values in the set divided by the total number of values. Because the mean is based on all the values in the data set, it is less likely to be affected by extreme values (outliers) than other measures of central tendency, such as the median or mode. In addition to being a balancing point in an observation, the mean has several other advantages as a measure of central tendency. For example, it is easy to calculate and is a useful tool for comparing different data sets. It can also be calculated from incomplete data, which is not the case with other measures of central tendency. Overall, the mean is the best measure of central tendency because it is a balancing point in an observation and takes into account all the values in a data set, making it less likely to be influenced by extreme values.

In an open economy, GNP (Gross National Product) is measured as: C + I + G + (X - M), where: - C represents private consumption expenditures by individuals and households. - I represents gross investment by businesses, such as spending on capital goods like machinery, buildings, and equipment. - G represents government spending on goods and services. - X represents exports, which are goods and services produced domestically and sold to foreign countries. - M represents imports, which are goods and services produced in foreign countries and purchased domestically. The formula above takes into account both domestic and foreign economic activities. The net difference between exports (X) and imports (M) is included to determine the impact of international trade on the economy. Therefore, by using the formula C + I + G + (X - M) to measure GNP in an open economy, we can get a better understanding of the overall economic activity, including the impact of international trade on the economy.

The bank type responsible for the formulation of rules and regulations guiding the banking industry is the Central bank. A central bank is an independent financial institution that oversees the monetary policy and banking system of a country. Its main functions include regulating commercial banks, managing the country's money supply, and controlling inflation. The central bank is also responsible for formulating rules and regulations that guide the banking industry, as well as ensuring compliance with these rules. In many countries, the central bank is the lender of last resort, meaning that it provides emergency loans to commercial banks in times of financial crisis. Examples of central banks include the Federal Reserve in the United States, the European Central Bank in Europe, and the Bank of Japan in Japan.

The business organization that is allowed to raise capital by sales of shares to more than twenty people is a Public limited liability company (PLC). A Public limited liability company is a type of business organization that is owned by shareholders who own shares of the company. These shares can be bought and sold by the general public, allowing the company to raise capital by selling shares to more than twenty people. In contrast, a Private limited liability company (Ltd) is a type of business organization that is owned by a small group of shareholders who are often family members or close friends. Private limited liability companies are not allowed to sell shares to the general public and are limited to selling shares to a maximum of 20 people. Partnerships and Sole proprietorships are not allowed to issue shares at all, as they are not considered separate legal entities from their owners. Instead, they raise capital by borrowing money from banks, investors or using their own funds.

The study of Economics becomes necessary because of the "scarcity of resources". Economics is the study of how societies use limited resources to satisfy their unlimited wants and needs. Because resources such as land, labor, and capital are limited, and human wants and needs are unlimited, there is always scarcity. Scarcity means that people have to make choices about what goods and services they will produce and consume because they cannot have everything they want. Therefore, the study of economics helps to provide a framework for making decisions about how to allocate scarce resources in the most efficient and effective way possible to maximize benefits to society. In conclusion, the study of economics becomes necessary because of the scarcity of resources, which creates the need to make choices and allocate resources efficiently to satisfy the unlimited wants and needs of society.

The invisible item in the list is "Banking services". In economics, visible items are tangible goods that can be physically seen and touched, while invisible items are intangible services that cannot be physically seen or touched. Petroleum services, processed rice, and processed milk are all visible items because they are tangible goods that can be seen, touched, and measured. On the other hand, banking services are intangible and cannot be physically seen or touched. Examples of banking services include providing loans, managing savings accounts, facilitating transactions, and offering financial advice. Therefore, banking services are considered an invisible item because they are intangible and cannot be physically seen or touched.

The reduction in the value of a country's currency in relation to the value of the currencies of other nations is known as "Devaluation". When a country's currency is devalued, it means that the value of its currency has decreased compared to the currencies of other countries. This can happen for a number of reasons, including a decrease in the demand for the country's goods and services, a decrease in the country's economic growth, or a decrease in the country's foreign reserves. A devaluation makes a country's exports cheaper and more competitive on the global market, which can help boost the country's economy. However, it can also lead to higher prices for imported goods, which can negatively impact the country's consumers. In simple terms, devaluation is when a country's currency becomes less valuable compared to other currencies.

Taxes and government expenditures are instruments of fiscal policy. Fiscal policy refers to the government's use of its spending and taxation powers to influence the economy. By adjusting the level of taxes and government spending, the government can influence the level of economic activity and control inflation. For example, if the government wants to stimulate economic growth, it may lower taxes and increase government spending. This increases consumer spending and investment, which can boost economic activity. On the other hand, if the government wants to slow down inflation, it may raise taxes and decrease government spending, which can reduce consumer spending and slow down economic growth. In summary, fiscal policy is a crucial tool used by governments to manage their economies and maintain economic stability.

The reward for capital refers to the return or compensation that an investor receives for providing their money as an investment in a business or project. This reward can take various forms, but some common ones are interest, rent, and dividends. Interest is a reward for lending money, and it is usually expressed as a percentage of the amount borrowed. For example, if you lend $1,000 to a company that promises to pay you 5% interest, you will receive $50 in interest payments each year. Rent is another form of reward for capital, and it is often associated with real estate. If you own a property and rent it out to tenants, you receive a regular income stream in the form of rent payments. This income can be a reward for the capital you have invested in the property. Risk is also a consideration when it comes to the reward for capital. Investments with higher risks may have the potential for higher returns, but they also have a greater chance of losing money. Therefore, investors who take on greater risk may expect a higher reward for their capital. Premium refers to an additional payment made to investors above and beyond their expected return. This may be offered to incentivize investment or to reward investors who are willing to take on greater risk or tie up their capital for a longer period of time. In summary, the reward for capital can take many forms, but it generally refers to the return that investors receive for putting their money to work in a business or investment. The specific form of the reward will depend on the type of investment and the risks involved.

An ad valorem tax is imposed on the value of a commodity. This type of tax is calculated as a percentage of the value of a product, rather than a fixed amount. For example, if a product is worth $100 and the ad valorem tax rate is 10%, the tax would be $10. The word "ad valorem" is Latin for "according to value". Ad valorem taxes are commonly used on consumer goods, such as clothing or electronics, and are applied at the point of sale. The purpose of this tax is to raise revenue for the government and to potentially regulate certain products by making them more expensive.

The coefficient of the price elasticity of supply is positive. This means that as the price of a good or service increases, the quantity of it that is supplied will increase as well. Conversely, if the price decreases, the quantity supplied will decrease. The degree to which the quantity supplied responds to changes in price is what the coefficient of the price elasticity of supply measures. A perfectly elastic supply has an elasticity of infinity, meaning that even a small change in price will result in a large change in the quantity supplied. On the other hand, a perfectly inelastic supply has an elasticity of zero, meaning that the quantity supplied does not change in response to price changes.
