Suppose I have two different possible routes for my commute to school. Because I never want to be late for class, I want to choose the route that provides a more consistent commute time. Being a hopeless statistician, I meticulously drove the first route 21 times and the ­second route 24 times and calculated the standard ­deviations for each. The data are as follows:
a. Using α = 0.05, determine if Route 1 provides a more consistent commute time than Route 2.
b. Verify your results using PHStat.
c. Interpret the p value obtained from the software.
