Consider the following hypothesis test H0 18 H0

Consider the following hypothesis test:

H0: μ ≤ 18

H0: μ > 18

A sample of 48 provided a sample mean x = 17 and a sample standard deviation s = 4.5.

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?
