Question
Please answer 1, 3, and 4 only
![7.35 FACIAL STRUCTURE OF CEOS. Refer to the Psychological
Science (Vol. 22, 2011) study on using a chief executive officer's
facial structure to predict a firm's financial performance,
Exercise 6.20 (p. 321). Recall that the facial width-to-height
ratio (WHR) for each in a sample of 55 CEOs at publicly traded
Fortune 500 firms was determined. The sample resulted in
= 1.96 and s = .15. An analyst wants to predict the financial
performance of a Fortune 500 firm based on the value of the true
mean facial WHR of CEOs. The analyst wants to use the value of
μ = 2.2. Do you recommend he use this value? Conduct a test of
hypothesis for u to help you answer the question. Specify all the
elements of the test: Ho, Ha, test statistic, p-value, a, and your
conclusion.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5322519d-7b19-4c41-9624-ce5f968b0c61%2F51aa872c-921a-48c1-894b-2416b194c16b%2Flnbwrq6_processed.png&w=3840&q=75)
