Consider a random sample of size one (n=1) from the distribution with probability function foy(0-1), if 0 0 otherwise. f(y; 0) = 0. (a) To test Ho: 0 = 8o versus H₁ : 0 = 0 > 00, find a most powerful test. Let the positive constant to define the rejection region of the test be k. (d) Graph the power function against for k= 0.3, 0.5, 0.8, and comment on how the power of the test changes as the values of k and change. (e) Is the above test in part (a) a uniformly most powerful test? Justify your answer.
