A sample of 39 customer deliveries was examined, and the average delivery time was found to be 41.3 minutes. Historically, the standard deviation for delivery time is 10.6 minutes. Using =0.05, 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. H0:H1: The z-test statistic is (Round to two decimal places as needed.) The critical z-score(s) is(are) (Round to two decimal places as needed. Use a comma to separate answers as needed.) Because the test statistic the null hypothesis. b. Determine the p-value for this test. The p-value is (Round to three decimal places as needed.)
