2. (18 points) Suppose that X" consists of iid data X1, ..., Xn with PDF pe, where 6 E O. Suppose there exists a function (x", 0) - To(x" ) with the property that En{To(X" ) } 1." Use Markov's inequality to show that the test has Type I error S a. (b) Again, for a fixed a E (0, 1), define the set estimator Ca(an ) = {VEO : To(x" )
