De nition I Typically, it is important to handle the case where the alternative hypothesis may be a composite one I It is desirable to have the best critical region for testing H 0 against each simple hypothesis in H 1 I The critical region C is uniformly most powerful (UMP) of size against H 1 if it is so against each simple hypothesis in H 1 I A test de ned by such a regions is a uniformly most. We examined the associations of these eight features with active aging and social connectedness through exploratory and confirmatory factor analyses.
