10.6 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. = 0.6. Use the binomial distribution. (a) Evaluate a assuming that p (b) Evaluate for the alternatives p = (c) Is this a good test procedure? 0.5 and p = 0.7. 10.7 Repeat Exercise 10.6 but assume that 200 adults are selected and the fail-to-reject region is defined to be 110 ≤ x ≤ 130, where is the number of college graduates in our sample. Use the normal approximation.
