A magazine claims that the brand of shoe you buy can have a major impact on how fast you run.  A researcher decides to test this assertion and gathers a group of seven (N=7) runners and asks each of them to run a mile wearing each of the four different types of shoes (Nike, Adidas, Asics, and Brooks) and records how quickly the runners complete their miles wearing each type of shoe.  Conduct a within subjects (AKA repeated measures) ANOVA, at alpha = 0.05,  to see if the runners mile times are significantly
