Johnny Cantalore, owner of Ba-Da-Bing Pizza, has a policy to put 36 slices of pepperoni on a large pizza. Cantalore recently hired two college students to work part-time making pizzas and decided to observe them at their jobs for a few days. Cantalore gathered the following data on number of pepperoni slices being used on the pizzas:
11: 00 A.M. to 5: 00 P.M.
Thirteen pizzas were made containing the following number of pepperoni slices:
36, 35, 41, 33, 35, 36, 34, 39, 44, 38, 32, 36, 35
5: 00 P.M. to 11: 00 P.M.
Twenty-five pizzas were made containing the following number of pepperoni slices:
36, 36, 41, 42, 37, 39, 44, 40, 44, 37, 48, 36, 35, 40, 39, 41, 31, 36, 36, 42, 45, 44, 37, 37, 36
