Question:
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:
Route 1 Route 2 Sample standard deviation 6.5 minutes 10.4 minutes Sample size 21 24
a. Using a = 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.
