Question 1 Report
The number of items produced by a company over a five- year period is given below:
| Year | 1978 | 1979 | 1980 | 1981 | 1982 |
| No produced | 4100 | 2500 | 1500 | 1800 | 9200 |
(i) Plot a bar chart for this information; (ii) What is the average production for the five- year period.
Answer Details
(i) Bar chart of company production
The bar chart below represents the number of items produced in each year. The horizontal axis shows the years and the vertical axis shows the number of items produced.
(ii) Average production
| Year | 1978 | 1979 | 1980 | 1981 | 1982 |
|---|---|---|---|---|---|
| Items produced | 4100 | 2500 | 1500 | 1800 | 9200 |
\[\text{Average production}=\frac{4100+2500+1500+1800+9200}{5}=\frac{19100}{5}=3820\]
Therefore, the average production for the five-year period is 3,820 items.
