Consider the following hypothesis test: H0: µ = 15 Ha: µ ≠ 15 A sample of 50 provided a sample mean of 14.15. The population standard deviation is 3. A.) Compute the value of the test statistic. (Round to two decimal places). B.) What is the p-value? (Round to three decimal places) C.) Using a=0.01, what is your conclusion? D.) Using the critical value approach for the 99% confidence level, what is the critical value? what is the rejection rule? what is your conclusion?
