Question

Question: Consider the following hypothesis test:

H₀ : µ = 18

H_a : µ ≠ 18

A sample of 25 provided a sample mean = 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?
