Consider the following hypothesis test.

H0: μ = 15

Ha: μ ≠ 15

A sample of 58 provided a sample mean x  = 14 and a sample standard deviation s = 6.3.

(a) Compute the value of the test statistic.

(b) Use the t distribution table to compute a range for the p-value.

(c) At α = 0.05, what is your conclusion?

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