Question 1

A supermarket sells rotisserie chicken at a fixed price per chicken rather than by the weight of the chicken.  The store advertises that the average weight of their chickens is 4.6 pounds.  A random sample of 30 of the store's chickens yielded the weights (in pounds) shown below.



Find and interpret the p-value in a test of H0: μ = 4.6 against  Ha: μ < 4.6.

Question 2

A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful only if the average time spent on a delivery does not exceed 30 minutes. The owner has randomly selected 17 customers and delivered pizzas to their homes in order to test whether the mean delivery time actually exceeds 30 minutes. What assumption is necessary for this test to be valid?
◦ The population of delivery times must have a normal distribution.
◦ The population variance must equal the population mean.
◦ None. The Central Limit Theorem makes any assumptions unnecessary.
◦ The sample mean delivery time must equal the population mean delivery time.
