Since the P -value, 0.117, is greater than α = 0.05, the engineer fails to reject the null hypothesis.

In such a case, T is in fact a UMP test for testing H0: p = p0 versus H1: p >p0. Lemma 6.1 Suppose that there is a test T of size a such that for every P1 2P1, T is UMP for testing H0 versus the hypothesis P = P1. Then T is UMP for testing H0 versus H1.
