8th-ed Chap 02, Sec 2.2, problem o15 A staff member at a local grocery store was assigned the job of inspecting all containers of yogurt in the store to determine the number of days to expiry date for each container. Containers that had already expired but were still on the shelves were given a value of 0 for number of days to expiry. The following table gives the frequency distribution of the number of days to expiry date. Number of days Number of Containers 0 to 5 30 6 to 11 12 to 17 42 18 to 23 24 to 29
