Question: A study using five samples finds that the mean of each sample is as follows: Sample 1 = 6.7; Sample 2 = 14.2; Sample 3

A study using five samples finds that the mean of each sample is as follows: Sample 1 = 6.7; Sample 2 = 14.2; Sample 3 = 13.8; Sample 4 = 10.4; Sample 5 = 15.8. Suppose that HSD (with q based on α = .05) for this study is 5.3.

(a) Which population means should be regarded as different from each other at the .05 level?

(b) Find the 95% CIs for comparing Sample 5 to each of the others.
