Question 1 a ) Construct a cumulative frequency distribution

Number of Cars | Frequency | Upper Boundary | Cumulative frequency | 15-19 | 9 | ≤19.5 | 9 | 20-24 | 8 | ≤24.5 | 17 | 25-29 | 4 | ≤29.5 | 21 | 30-34 | 4 | ≤34.5 | 25 | 35-39 | 6 | ≤39.5 | 31 | 40-44 | 4 | ≤44.5 | 34 | 45-49 | 1 | ≤49.5 | 36 |

b) Cumulative Frequency Polygon

c) Months does the dealer sell less than 20 cars is9 months

d) Percentage of months with more than 30 cars sold

= 15/ 36 (100%)
= 41.67 %
