Berdine’s Chicken Factory has several stores in the Hilton Head, South Carolina, area. When interviewing applicants for server positions, the owner would like to include information on the amount of tip a server can expect to earn per check (or bill). A study of 500 recent checks indicated the server earned the following amounts in tips per 8-hour shift.

$0 up to $ 20........ 200
20 up to 50........ 100
50 up to 100........ 75
100 up to 200........ 75
200 or more ........ 50
