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?
