77. Let denote the probability of Type II error. For an o = .05-level test of Ho: p=0 against Hu> based on n = 30 observations = 36 at =4. Select the correct response(s).

a) At = 5, 8 > .36.

b) If a01, then at A = 4, B>.36.

c) If = 50, then al = 4. > .36.

d) The power of the test is .64 at = 4.

e) This must be false, because necessarily a +B=1
