your pizza in 33 minutes from when the order is placed. Being a skeptic, you decide to test and se mean delivery time is actually more than 35 minutes. For the simple random sample of 14 customers who record the amount of time it takes ch of their pizzas to be delivered, the mean is 37.0 minutes with a standard deviation of 9.9 minutes. Assume that the population distribution proximately normal. Perform a hypothesis test using a 0.05 level of significance. 3 of 3: Draw a conclusion and interpret the decision.

A pizza delivery chain advertises that it will deliver your pizza in 35 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 35 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 37.0 minutes with a standard deviation of 9.9 minutes. Assume that the population distribution is approximately normal. Perform a hypothesis test using a 0.05 level of significance. Step 3 of 3: Draw a conclusion and interpret the decision. 4
