Question:

Refer to Exercise 11.S.12. Assuming all possible comparisons of group means will be computed, use the Bonferroni method to construct a 95% confidence interval for the effect of probucol in the absence of multivitamins. That is, construct a Bonferroni-adjusted 95% (aew = 0.05) confidence interval for μprobucol - μplacebol
