# Question

With reference to Exercise 13.42, test at the 0.02 level of significance whether it is reasonable to assume that the two populations sampled have equal variances.

In exercise

To compare two kinds of front- end designs, six of each kind were installed on a certain make of compact car. Then each car was run into a concrete wall at 5 miles per hour, and the following are the costs of the repairs (in dollars):
