2. Suppose that X1, X2, ., X, are iid N(u, o?). To test the null hypothesis Ho: µ = Ho, the t-test is often used: X - Ho t : Vn Under Ho, t follows at distribution with n-1 degrees of freedom. Show that the likelihood ratio test of this null hypothesis is equivalent to the t-test. [Hint: show that the rejection region for the likelihood ratio test is the same as the rejection region as for t-test above.]
