Problem 7.1

Problems 7.1 and 7.3 were inspired by one of the authors (Cody) watching the French Open Tennis tournament while working on problem sets. (McEnroe versus Lendl (1984). Lendl won in five sets.)

Three brands of tennis shoes are tested to see how many months of playing would wear out the soles. Eight pairs of brands A, N, and T are randomly assigned to a group of 24 volunteers. TIle following table shows the results of the study:

Are the brands equal in wear quality? Write a SAS program to solve this problem, using ANOYA. Include the statements to perform an SNK multiple comparison.
