A pizza delivery chain advertises that it will deliver your pizza in 25 minutes from when the order is placed. Being a skeptic, you decide to test and see if the mean delivery time is actually more than 25 minutes. For the simple random sample of 12 customers who record the amount of time it takes for each of their pizzas to be delivered, the mean is 27.4 minutes with a standard deviation of 6.5 minutes. Assume that the population distribution is approximately normal. Perform a hypothesis test using a 0.01 level of significance. Draw a conclusion and interpret the decision.
