μ1, μ2, and μ3 are the means of normal distributions with an equal but unknown variance. Our goal is to test H0: μ1 = μ2 = μ3 vs Ha: at least two μj are different, by taking random samples of size 4 from each distributions. Let x1 = 28, x2 = 46, x3 = 34, and ??x2ij =1038 (a) Construct an ANOVA table. (b) Carry out the 5% significance level test. (c) What is the HSD in this problem?
