46. Refer to the hypotheses in Example 6.11. Suppose a sample of size 25 were taken (in- stead of 36) and suppose the estimated standard error of Y is o = 3.6. When a = .05. compute the probabilities of a Type II error for the altcmative u values of

(a) 5.

(b) 10,

(c) 15. Compare these to the probabilities of Type II error when ; = 3.0. and use them to illustrate the effect of the sample size on P(Type II erroi).
