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 X = 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 to help you answer the question. Specify all the elements of the test: H₁, H₂, test statistic, p-value, a, and your μl conclusion. Additional questions: For a = 0.05, please specify: 1. The parameter of interest. 2. Ho and Ha 3. Test statistic and its sampling distribution 4. Rejection region (RR) and your conclusion based on RR 5. p-value and your conclusion based on p-value
