The November 2004 issue of the magazine “Ohio Game and Fish” included an article that predicted the outlook of Ohio’s top 20 trophy deer counties for the 2004 whitetail deer-hunting season. The counties were ranked by several factors including the 2002 trophy deer qualifiers and the number of deer that qualified for the “Buckeye Big Buck Club” as shown in the table below. Use the table to create a basic stem-and-leaf plot of the total BBBC qualifiers, and then answer the next five questions. |
