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. Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. (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. For the alternative p=0.2, p = 0.0210. (Round to four decimal places as needed.) For the alternative p = 0.4. B= (Round to four decimal places as needed.)
