The proportion of adults living in a small town who are college graduates is estimated to be p=0.3. To test this hypothesis, a random sample of 200 adults is selected. If the number of college graduates in the sample is anywhere in the fail-to-reject region defined to be 52 ≤x≤ 68, where x is the number of college graduates in our sample, we shall not reject the null hypothesis that p = 0.3; otherwise, we shall conclude that p# 0.3. Complete parts (a) through (c) below. Use the normal approximation.

(a) Evaluate a assuming that p = 0.3. a=0.1896 (Round to four decimal places as needed.) (b) Evaluate ẞ for the alternatives p=0.2 and p=0.4.
