Take Quiz Exit A Psychological Science researcher uses 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 65 CEOs at publicly traded Fortune 500 firms was determined. The sample resulted in x = 1.93 and s = .24. The 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 test if the true population mean of WHR is M = 2.0. Use a = .06. What is the critical value?
