A pizza delivery chain advertises that it will deliver your pizza in 20 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 20 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 22.0 minutes with a standard deviation of 1.9 minutes. Assume that the population distribution is approximately normal. Perform a hypothesis test using a 0.01 level of significance. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Ho : μ = 20 Hap. 20
