Solved: Suppose that Y1, Y2,..., Yn constitute a random sample from a normal
Chapter 10, Problem 10.94(choose chapter or problem)
Suppose that Y1, Y2,..., Yn constitute a random sample from a normal distribution with known mean and unknown variance 2. Find the most powerful -level test of H0 : 2 = 2 0 versus Ha : 2 = 2 1 , where 2 1 > 2 0 . Show that this test is equivalent to a 2 test. Is the test uniformly most powerful for Ha : 2 > 2 0 ?
