Consider the following hypothesis test: H0: μ = 18 Ha: 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?
