The proportion of adults living in a small town who are college graduates is estimated to be p = 0 .6. to test this hypothesis, a random sample of 15 adults is selected. if the number of college graduates in the sample is anywhere from 6 to 12, we shall not reject the null hypothesis that p = 0.6; otherwise, we shall conclude that p≠0.6 (a) evaluate α assuming that p = 0.6. use the binomial distribution. (b) evaluate β for the alternatives p = 0 .5 and p = 0 .7. (c) is this a good test procedure?
