For five independent groups, assume that you plan to do all pairwise comparisons of the means and you want FWE to be 0.05. Further assume that n1 = n2 = n3 = n4 = n5 = 20, ¯X1 = 15, ¯X2 = 10, s21

= 4, and s22

= 9, s23

= s24

= s25

= 15, test H0 : μ1 = μ2 using

(a) Fisher’s method

(assuming the ANOVA F test rejects),

(b) Tukey-Kramer,

(c) Dunnett’s T3,

(d) Games-Howell,

(e) Scheff´e’s method,
