Problem Set 1.) Around Durham College there are four pizza parlors that make deliveries. A researcher decides to compare how promptly the four parlors deliver. On six randomly chosen nights, she orders a large pepperoni pizza from each parlor, then records the elapsed time until the pizza is delivered to her apartment. Assume that her apartment is approximately the same distance from the four pizza parlors. The following table shows the time (in minutes) for these deliveries. Assume that all assumptions required to apply one-way ANOVA hold true. Pizza Pizza Pizza Hut Papa John Dominoes 20.0 22.1 22.3 23.9 24.0 27.0 26.0 24.1 18.3 20.2 24.0 25.8 22.0 32.0 30.1 29.0 20.8 26.0 28.0 25.0 19.0 24.8 25.8 24.2 Does the mean delivery time the same for each of the four pizza parlor using the 5% significance level?
