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 7 customers who record the amount of time it takes for each of their pizzas to be delivered, the mean is 32.6 minutes with a standard deviation of 2.1 minutes. Assume that the population distribution is approximately normal. Perform a hypothesis test using a 0.10 level of significance. I ofs Step 3 of 3: Draw a conclusion and interpret the decision. Answer O Tables Кeypad Keyboard Shortcuts O We reject the null hypothesis and conclude that there is sufficient evidence at a 0.10 level of significance that the mean delivery time is actually more than 30 minutes. We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 0.10 level of significance that the mean delivery time is actually more than 30 minutes. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.10 level of significance that the mean delivery time is actually more than 30 minutes. O We reject the null hypothesis and conclude that there is insufficient evidence at a 0.10 level of significance that the mean delivery time is actually more than 30 minutes.
