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

The concept of division of labor is usually associated with Adam Smith, a Scottish economist who lived in the 18th century. Smith is known as the father of modern economics and his book "The Wealth of Nations" is considered a landmark in the history of economic thought. Division of labor is the process of breaking down the production of goods or services into smaller tasks, with each worker specializing in a particular task. Smith argued that this specialization allows workers to become more efficient and productive, as they become more skilled at their specific task over time. He famously used the example of a pin factory to illustrate the benefits of division of labor, showing how the productivity of the workers could be increased by breaking down the process of pin-making into smaller, specialized tasks. Smith believed that the division of labor not only increased productivity, but also led to economic growth and prosperity. By allowing each worker to focus on their specific task, and by encouraging trade and exchange between different workers and regions, the economy as a whole could become more efficient and produce more goods and services. This, in turn, would lead to greater wealth and prosperity for society as a whole. Overall, Smith's ideas about the division of labor had a profound impact on the development of modern economics and are still widely studied and discussed today.

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.

When a union is composed of workers with the same skill, it is called a craft union. This means that the union represents workers who have the same type of training or expertise in a particular craft or trade. For example, a union of electricians, plumbers, or carpenters would be considered craft unions. These workers often have specific skills that are honed through years of training and experience, and the craft union helps to protect their interests, such as negotiating better wages, benefits, and working conditions. By focusing on a specific skill, craft unions can advocate for their members' unique needs and ensure that they receive fair treatment in the workplace.

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.

Efficiency of labour may be defined as the ability of labour to increase output without increasing the quantity of labour. Increase in efficiency is usually expressed in terms of increase in output of labour within a shorter period of time without any fall in the quality of goods and services produced. Factors which affect efficiency of labour include Education and training, attitude to work, working conditions of workers. However, total population is not a factor that affects efficiency of workers.

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 term used to describe the number of people who are qualified to work and who offer themselves for employment is called the "Working Population". The working population refers to individuals who are of working age and are either employed or actively seeking employment. This group of people is considered to be the supply of labor in the economy and is an important factor in determining the overall health and stability of the labor market. It's important to note that the working population can be influenced by various factors such as migration, education levels, and the availability of job opportunities. Understanding the size and composition of the working population can provide valuable insights into the current state of the labor market and can inform decisions related to economic and labor policies.

The economic term used to refer to human wants, desires, or needs is "Ends". In economics, ends refer to the goals or objectives that individuals or society aims to achieve. These are the things that people want or need, such as food, shelter, clothing, entertainment, or education. Ends are considered to be unlimited because there are always new wants or needs that arise as people's tastes and preferences change, as well as advances in technology and innovation. However, the resources to satisfy these ends are limited, which creates a problem of scarcity. To achieve these ends, individuals must use alternative means, or resources, such as labor, capital, or natural resources. Therefore, the correct option is "Ends".

The two major types of international trade are bilateral trade and multilateral trade. Bilateral trade refers to the exchange of goods and services between two countries. It involves the negotiation and agreement of terms and conditions between two parties, and it usually results in a trade surplus or deficit for each country. On the other hand, multilateral trade involves the exchange of goods and services among three or more countries. This type of trade is governed by international trade agreements, such as the World Trade Organization, and aims to promote free trade and economic cooperation among member countries. In summary, bilateral trade involves trade between two countries, while multilateral trade involves trade among three or more countries and is governed by international trade agreements.

The reward for capital is interest. Capital refers to the money or assets that are used to invest in a business or enterprise. When someone invests their capital into a business, they expect to earn a return on their investment. The return on investment for capital is called interest. Interest is the amount of money paid by the borrower to the lender for the use of their capital. This can be in the form of regular interest payments or a lump sum at the end of the investment period. The interest rate is determined by various factors such as market conditions, inflation, and risk. Therefore, interest is the primary reward for capital.

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 form of utility that refers to the enhancement of a commodity's usefulness by moving it from a place where it has little utility to another area where its utility is higher is called "place utility." For example, a bottle of water may have low utility in a store shelf where there is an abundance of water, but it would have a higher utility in a desert where water is scarce. By moving the water bottle from the store shelf to the desert, the place utility of the water bottle is increased. On the other hand, marginal utility refers to the additional satisfaction or benefit that a person derives from consuming an extra unit of a good or service, while form utility refers to the value added to a commodity by transforming it into a more useful form, such as processing raw materials into finished products. Total utility, on the other hand, refers to the overall level of satisfaction or benefit that a person derives from consuming a particular quantity of a good or service.

The major form of migration that tends to create problems in developing countries is rural-urban migration. This refers to the movement of people from rural areas to urban areas in search of better economic opportunities and a higher standard of living. There are several reasons why rural-urban migration occurs. In rural areas, there may be limited job opportunities, low wages, and a lack of access to basic services such as healthcare, education, and clean water. In contrast, urban areas offer more job opportunities, higher wages, and better access to services. However, rural-urban migration can create several problems. Firstly, it can lead to overcrowding and strain on urban infrastructure, such as housing, transportation, and public services. This can result in poor living conditions for migrants and contribute to the spread of diseases. Secondly, rural-urban migration can lead to social problems such as crime, poverty, and inequality. Migrants may face discrimination and difficulty integrating into urban communities, which can exacerbate social tensions. Finally, rural-urban migration can have negative impacts on rural areas, as it can result in a loss of skilled workers and a decline in agricultural productivity. This can have serious consequences for food security and rural development. Overall, while rural-urban migration can provide benefits for migrants in terms of economic opportunities and access to services, it can also create significant challenges for both urban and rural areas.

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.

Diminishing returns set in at point T in the production function. In a production function, adding more units of input (such as labor or capital) typically leads to an increase in output at a certain rate. However, as the amount of input increases beyond a certain point, the rate of output increase begins to decline. This is known as the law of diminishing returns. In the diagram, points R and S represent the increasing phase of the production function where output increases at an increasing rate as more input is added. However, at point T, the rate of increase in output begins to slow down, indicating that the law of diminishing returns has set in. Beyond point T, adding more input will result in smaller increases in output, and may even cause a decrease in output if the input becomes too excessive, as shown by point V. Therefore, point T is where diminishing returns set in, indicating the optimal level of input for maximum output.

When the elasticity of demand is zero, the demand curve is said to be perfectly inelastic. This means that a change in price will not cause any change in the quantity demanded. In other words, no matter how much the price changes, the quantity demanded will remain the same. For example, if the price of insulin for diabetes treatment were to double, people who depend on it to survive would have no choice but to continue buying the same amount. This is because they cannot reduce their consumption of insulin, and therefore, the demand for insulin is perfectly inelastic. In terms of the demand curve, a perfectly inelastic demand curve is vertical, meaning that it is a straight line perpendicular to the horizontal axis. This is because, as mentioned earlier, the quantity demanded remains constant regardless of the price. So, when graphed, the demand curve will be a straight vertical line.

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.
