An airport with five security check points wants to compare the mean times that passengers have to wait to get through airport security between 8AM and 9AM on Monday morning among the five check points. Data File Wait Times - PSIII gives the wait times for six randomly selected passengers arriving between 8 and 9 AM on a Monday morning at each of the check points.

a. Assuming the requirements of ANOVA are satisfied, at the .05 level of significance, is there evidence of a significant difference among the mean wait times at the five checkpoints?

Complete the following:
1. State H0.
2. State H1.
3. State the value of α.
4. State the value of the test statistic.
5. State the p-value.
6. State the decision in terms of H0 and why.
7. State the decision in terms of the problem.

b. If appropriate, state which of the check points are significantly different in terms of mean wait times.

c. Based on the results of part a, if a passenger has a choice and wants to minimize wait time, which check point or check points should he or she choose?
