Traveler’s Insurance would like to investigate if the average number of miles driven per month by a male teenage driver exceeds the average number of miles driven per month by a female teenage driver. The following data summarizes the sample statistics for the miles driven per month by each gender.

a. Recall that testing for a difference between two population means requires an assumption about population variances. Perform a hypothesis test using α = 0.10 to determine if the population variance for miles driven per month is different for teenage males and teenage females.

b. Verify your results using PH_Stat.

c. Identify the p value from part b and interpret the result.
