⟩ What are the steps in hypothesis testing?
An experiment is described by an exponential random variable with mean ? and x1 and x2. A proposed test of the hypothesis ?=2 against the alternative ?=½ uses the critical region {(x1, x2): min(x1, x2) <¼} Show that this test has size of approximately 0.22 and find its power. Obtain a better test of the same size
