In practice, you should use a one‐tailed test only when you have good reason to expect that the difference will be in a particular direction. A two‐tailed test is more conservative than a one‐tailed test because a two‐tailed test takes a more extreme test statistic to reject the null hypothesis. Previous Quiz: The Test ... WebA test T of size a is a uniformly most powerful (UMP) test if and only if bT (P) bT(P) for all P 2P1 and T of level a. Using sufﬁcient statistics If U(X) is a sufﬁcient statistic for P 2P, then for any test T(X), E(TjU) has the same power function as T and, therefore, to ﬁnd a UMP test we may consider tests that are functions of U only. henrico holiday schedule
