2. Let M1, M2, M3 be the means of 3 normal distributions with common but unknown variance o2. We wish to test at significance level a = 0.05 the hypothesis Ho : M1 = M2 = M3 against Hi : all alternatives. To do so, we draw independent random samples from these distributions. Determine whether we retain or reject H, if the observed values from these distributions are, respectively, 17 20 18 16 19 X2: 21 23 20 18 19 X3: 15 12 13 16 You should do the calculations by hand or with a calculator and indicate the calculations in your answer.
