Question: For four independent groups, assume that you plan to do all pairwise comparisons of the means and you want FWE to be .05. Further assume

For four independent groups, assume that you plan to do all pairwise comparisons of the means and you want FWE to be .05. Further assume that n1 = n2 = n3 = n4 = n5 = 10 X¯ 1 = 20, X¯ 2 = 12, s 2

1 = 5, s 2

2 = 6, s 2

3 = 4, s 2

4 = 10, and s 2

5 = 15.
