Cybersecurity is a critical business issue that demands the attention of business and IT executives. According to a recent study. 67% of surveyed business and IT executives reported phishing scams at their institutions. Complete parts (a) and (b) below. a. If you conduct a follow-up study to estimate the population proportion of business and IT executives reporting phishing scams at their institutions, would you use a p of 0.67 or 0.50 in the sample size formula? OA Use p=0.50 because this value will produce the greater sample size. B. Use p=0.67 because this value is an educated estimate of x OC. Use p=0.50 because this value is an educated estimate of OD. Use p=0.67 because this value will produce the greater sample size. b. Using your answer to (a), find the sample size necessary to estimate, with 90% confidence, the population proportion to within 10.04. The sample size needed is (Round up to the nearest integer.)
