Let _1, _2, _3 be, respectively, the means of three normal distributions with a common but unknown variance _2. In order to test, at the _ = 5% significance level, the hypothesis H0 : _1 = _2 = _3 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 […]
