2. An AppleBee's waiter thinks the mean cost one person spends to eat supper (meals 6pm and after) is higher than $13.50. He takes a random sample of 45 orders that has a sample mean of $14.03 with a standard deviation of $2.84. Is this enough evidence to conclude that the mean cost for a meal exceeds $13.50? Use a significance level of 0.05. a. State the null and the alternative hypotheses. b. Calculate the value of the test statistic. c. Find the p-value using the test statistic. d. Using the p-value, decide if the null hypothesis can be rejected and answer the original question concerning the mean cost of all orders. Does the mean cost of all orders exceed $13.50?
