You may need to use the appropriate appendix table or technology to answer this question.

In the past, the average age of employees of a large corporation has been 39 years. Recently, the company has been hiring older individuals. In order to determine whether there has been an increase in the average age of all the employees, a sample of 64 employees was selected. The average age in the sample was 45 years with a standard deviation of 16 years. Let

? = 0.05.

(a)

State the null and the alternative hypotheses (in years). (Enter != for ≠ as needed.)

H₀:

H_a:

(b)

Compute the test statistic.

(c)

Using the p-value approach, test to determine whether or not the mean age of all employees is significantly more than 39 years.

Find the p-value. (Round your answer to four decimal places.)

p-value =

State your conclusion.

Do not reject H₀. There is insufficient evidence that the mean age of all employees is significantly more than 39 years.Reject H₀. There is insufficient evidence that the mean age of all employees is significantly more than 39 years. Reject H₀.
