A psychology student conducted a study on using a chief executive officer's facial structure to predict a firm's financial performance. The facial width-to-height ratio (WHR) for each in a sample of 51 CEOs at publicly traded firms was determined. The sample resulted in x = 2.26 and s= 0.65. The student wants to predict the financial performance of a firm based on the value of the true mean facial WHR of CEOs. The student wants to use the value of μ = 2.1. Do you recommend he use this value? Conduct a test of hypothesis for μ to help you answer the question. Specify all the elements of the test, including Ho, Ha test statistic, p-value, and your conclusion. Test at a = 0.05.
