Textbook Question

Chapter 11, Problem 3SE

Bonferroni Correction (Example 1) Suppose you have five groups of observations, and you do hypothesis tests (t-tests) to compare all possible pairs of means.

a. How many pairwise comparisons can be done with five groups? List all comparisons with five

groups labeled A, B, C, D, and E, starting with AB, AC, and so on.

b. Using the Bonferroni Correction, what significance level should you use for each hypothesis

test if you want an overall significance level of 0.05?
