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.

(i)

(ii) Average production in the period

= \(\frac{4100 + 2500 + 1500 + 1800 + 9200}{5}\)

= \(\frac{19100}{5}\)

= \(3820\)
