To evaluate whether three of its slopes should be classified as equally difficult, a ski resort sets up an experiment in which three skiers from each skill category (A beginner to F = expert) are randomly assigned to make one run on the slope to which they have been assigned.
Given the times (minutes) in file XR14040, and using the 0.05 level of significance, can it be concluded that the slopes could be equally difficult? Identify and interpret the p-value for the test.
