A pizza delivery chain advertises that it will deliver your pizza in 40 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 40 minutes. For the simple random sample of 6 customers who record the amount of time it takes for each of their pizzas to be delivered, the mean is 48.2 minutes with a standard deviation of 10.6 minutes. Assume that the population distribution is approximately normal. Perform a hypothesis test using a 0.10 level of significance.
