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 “bar” as a restaurant on an expense report, and 19% have caught salespeople giving a kickback to a customer. To convert the data into useful information, construct a 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report, determine the critical value, and sampling error. Explain what management can learn from the 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report.
