# Question

The following data represent the number of licensed drivers in various age groups and the number of fatal accidents within the age group by gender.

(a) On the same graph, draw a scatter diagram for both males and females. Be sure to use a different plotting symbol for each group. For example, use a square (□) for males and a

plus sign (+) for females. Treat number of licensed drivers as the explanatory variable.

(b) Based on the scatter diagrams, do you think that insurance companies are justiﬁed in charging different insurance rates for males and females? Why?

(c) Compute the linear correlation coefﬁcient between number of licensed drivers and number of fatal crashes for males.

(d) Compute the linear correlation coefﬁcient between number of licensed drivers and number of fatal crashes for females.

(e) Which gender has the stronger linear relation between number of licensed drivers and number of fatal crashes. Why?
