2. Suppose we have Xl, ... , We are interested in a hypotheses test with (a) Suppose n = 1. Consider C = {Xl > 3}. What is the significance level of this test? Hint: the CDF of X, F(X) = x) is given by (b) S1113130Re n = 49. Use. CLT to find the. appro:ri.ma.t.e. signfiea.nee level of the test C = { xz : 63}. (c) What is the approximate power of the test C = {Xi : Xi > 63} when true O is 2/3? Usc CLT to answer this question.
