QUESTION:

Problem 35E

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. 310). 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 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 = 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: H0, Ha, test statistic, p-value, a, and your conclusion.

ANSWER:

Solution :

Step 1 of 1:

From the given information we know that $\overline{x}=1.96$ and the standard deviation s=0.15.

The sample size n is 55.

Then the analyst wants to use the value of $\mu{}=2.2$ .

Our goal is:

We need to specify all the elements of the test ${H}_{0}$ , ${H}_{a}$ , test statistic, p-value, $\alpha{}$ and your conclusion.

We know that the true mean facial width-to-height ratio is $\mu{}$ .

From the given information we know that
