SCENARIO 8-10
A sales and marketing management magazine conducted a survey on salespeople cheating on their
expense reports and other unethical conduct. In the survey on 200 managers, 58% of the managers
have caught salespeople cheating on an expense report, 50% have caught salespeople working a
second job on company time, 22% have caught salespeople listing a "strip bar" as a restaurant on an
expense report, and 19% have caught salespeople giving a kickback to a customer.
-Referring to Scenario 8-10, determine the sample size needed to estimate the proportion of
managers who have caught salespeople working a second job on company time to within $\pm 0.02$ with
95% confidence.
