55

CEOs at publicly traded firms was determined. The sample resulted in

x=1.74

and

s=2.02.

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=2.3.

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

H0​,
Ha​,

test​ statistic, p-value, and your conclusion. Test at

α=0.10.
 
Find the​ p-value.
