Statement of a problem № m40755


Assume that X1, . . . , Xn are i.i.d. with the normal distribution that has mean μ and variance 1. Suppose that we wish to test the hypotheses H0: μ ≤ μ0, H1: μ>μ0. Consider the test that rejectsH0 if Z ≥ c, where Z is defined in Eq. (9.1.10). a. Show that Pr(Z ≥ c|μ) is an increasing function of μ. b. Find c to make the test have size α0.
