Let 1 , 2 , 3 be, respectively, the means of three normal distributions

Question:

Let μ1, μ2, μ3 be, respectively, the means of three normal distributions with a common but unknown variance σ2. In order to test, at the α = 5% significance level, the hypothesis H0 : μ1 = μ2 = μ3 against all possible alternative hypotheses, we take an independent random sample of size 4 from each of these distributions. Determine whether we accept or reject H0 if the observed values from these three distributions are, respectively,
