WebIf the engineer used the P -value approach to conduct his hypothesis test, he would determine the area under a tn - 1 = t24 curve and to the right of the test statistic t * = 1.22: In the output above, Minitab reports that the P -value is 0.117. Since the P -value, 0.117, is greater than α = 0.05, the engineer fails to reject the null hypothesis.

WebJan 31, 2024 · The formula for the two-sample t test (a.k.a. the Student’s t-test) is shown below. In this formula, t is the t value, x1 and x2 are the means of the two groups being compared, s2 is the pooled standard error of the two groups, and n1 and n2 are the number of observations in each of the groups. WebAn interesting phenomenon in Example 6.2 is that the UMP test T does not depend on p1. 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. Proof T
