Transcribed Image Text: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 if the average time spent on the deliveries does not exceed 25 minutes.
The owner has randomly selected 18 customers and has delivered pizzas to their
homes in order to test if the mean delivery time actually exceeds 25 minutes. What
assumption is necessary for this test to be valid?

O The sample mean delivery time must equal the population mean delivery time.
O None. The Central Limit Theorem basically makes any assumptions unnecessary.
The population of delivery times must have a normal distribution.
The population variance must equal the population mean.
