Question

One area that fast food restaurants compete with one another is with the service time for the drive through window. The following data show the drive through service times, in minutes, for a random sample of customers at three fast food chains. These data can also be found in the Excel file drive through service. xlsx.
a. Perform a one way ANOVA using α = 0.01 to ­determine if a difference exists in the average drive through service time between these three restaurants.
b. If appropriate, perform a multiple comparison test to determine which pairs are different using α = 0.01.
c. Verify your results using Excel or PHStat.
