Let X 1 ,X 2 ,X 3 be i.i.d. from Binomial B (1 ,p ). Derive the uniformly most powerful unbiased (UMPU) test for testing the hypothesis H : p = 0 . 25 v.s. the alternative H A : p 6 = 0 . 25 at level of signicance . Determine the test for = 0 . 05. [Hint: Let Y B (3 , . 25), then P ( Y = 0) = 0 . 42, P ( Y = 1) = 0 . 42, P ( Y = 2) = . 14, and P ( Y = 3) = 0 . 02] 1...
