(Control chart) Clinton Pizza recently hired several college students to work part-time making pizzas. Robert Clinton, the owner, has the policy to put 36 slices of pepperoni on a pizza, but (given diversity in size) he sometimes puts on between 34 and 38. After observing the students for a few days, Robert gathered the following data on number of pepperoni slices:

11:00 a.m. to 5:00 p.m.

13 pizzas were made containing the following number of pepperoni slices: 35, 37, 41, 33, 36, 36, 35, 39, 44, 37, 36, 36, 35 5:00 p.m. to 11:00 p.m.

25 pizzas were made containing the following number of pepperoni slices: 35, 37, 41, 42, 36, 39, 44, 43, 44, 37, 48, 36, 35, 40, 39, 41, 29, 36, 36, 42, 45, 44, 37, 36, 36
