A pizza place recently hired additional drivers and as a result now claims that its average delivery time for orders is under 43 minutes. A sample of 40 customer deliveries was examined, and the average delivery time was found to be 40.2 minutes. Historically, the standard deviation for delivery time is 11.7 minutes. Using a = 0.10, complete parts a and b below. a. Does this sample provide enough evidence to support the delivery time claim made by the pizza place? Determine the null and alternative hypotheses.
