A pizza delivery chain advertises that it will deliver your pizza in 30 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 30 minutes. For the simple random sample of 14 customers who record the amount of time it takes for each of their pizzas to be delivered, the mean is 31.8 minutes with a standard deviation of 8.6 minutes. Assume that the population distribution is approximately normal. Perform a hypothesis test using a 0.025 level of significance. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. H0Ha: =30: 30

Assume that the population distribution is approximately normal. Perform a hypothesis test using a 0.025 level of significance.

Step 2 of 3:

Compute the value of the test statistic. Round your answer to three decimal places.
