Part V: 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) Assume that 200 adults are selected, and the fail-to-reject region is defined to be 110

Question
Part V:
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) Assume that 200 adults are selected, and the fail-to-reject region is defined
to be 110 <x< 130, where x is the number of college graduates in our
sample. Use the normal approximation.
