Consider the following hypothesis test:

H0: μ =18
Ha: μ =18
A sample of 48 provided a sample mean = 19 and a sample standard deviation s =4.7.
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 = .01, what is your conclusion?
d. What is the rejection rule using the critical value? What is your conclusion?
