A commuter is trying to decide whether there is a difference in the amount of time it takes him to drive to work, depending on departure time in the morning. He keeps track of the number of minutes his commute takes him, on a random sample of days, with three departure times: 6 A.M., 7 A.M., and 8 A.M. Check to see whether the conditions required for one way ANOVA are met. If they are, conduct a test of hypothesis at the 5% level of significance to determine whether the mean commuting times are equal.
