The proportion of adults living in a small town who are highschool graduates is estimated to be p equal to 0.5. To test this hypothesis, a random sample of 14 adults is selected. If the number of highschool graduates in the sample is anywhere from 6 to 12, we shall not reject the null hypothesis that p is equal to 0.5, otherwise, we shall conclude that p is not equal to 0.5. Evaluate the value of alpha.
