24. Consider the following hypothesis test:

H0:

Ha:

m 5 18 m ± 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 a = .05, what is your conclusion?

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