Extracted text: 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 45 CEOS at publicly traded firms was determined. The sample resulted in x= 1.72 and s = 1.19. The student wants to predict the inancial 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 u 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 = 0.01. What are the null and alternative hypotheses? O A. Ho: Ho = 2.1 H3: Ho <2.1 o="" b.="" ho:="" ho="2.1" h3:="" ho="" #2.1="" ос.="" но:="" но="" #2.1="" o="" d.="" ho:="" ho="2.1" h3:="" ho=""> 2.1 H3: Ho =2.1
