A one-factor fixed-effects ANOVA is performed on data from three groups of equal size (n = 15) and equal variances, and H₀ is rejected at the .05 level. The following values were computed: MS_with = 60 and the sample means are $\bar{Y}_{.1}$ = 25, $\bar{Y}_{.2}$ = 20, and $\bar{Y}_{.3}$ = 12. Use the Tukey HSD method to test all possible pairwise contrasts ($\alpha$= .05).
