The proportion of adults living in a small town who are college graduates is estimated to be p = 0.4. To test this hypothesis, a random sample of 100 adults is selected. If the number of college graduates in the sample is anywhere in the fail-to-reject region defined to be 30 ≤x≤50, where x is the number of college graduates in our sample, we shall not reject the null hypothesis that p = 0.4; otherwise, we shall conclude that p# 0.4. Complete parts (a) through (c) below. Use the normal approximation. Click here to view page 1 of the standard normal distribution table.
