Consider the following hypothesis test: H0: 12 H0: > 12 A sample of 25 provided a sample mean x = 14 and

Consider the following hypothesis test:

H0: μ ≤ 12

H0: μ > 12

A sample of 25 provided a sample mean x = 14 and a sample standard deviation s = 4.32.

a. Compute the value of the test statistic.

b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value.

c. At α = .05, what is your conclusion?

d. What is the rejection rule using the critical value? What is your conclusion?
