1. A statistics practitioner has performed an analysis of variance, using Alpha = 0.05, followed by a multiple comparisons test to compare the means of three populations (AAA, BBB, and CCC). The results of the analysis are shown here: a. Must we accept that all three population means are equal? Why or why not? b. What does the multiple comparisons test reveal? 2. I am using ANOVA to analyze the means of 4 populations. I want the true probability of a Type I error to be no more than 7.5%. Calculate Alpha using the Bonferroni adjustment
