Rob Whitner is the owner of Whitner Autoplex. Rob’s father founded the dealership in 1964, and for more than 30 years, they sold exclusively Pontiacs. In the early 1990s, Rob’s father’s health began to fail, and Rob took over more of the day-to-day operation of the dealership. At this same time, the automobile business began to change—dealers began to sell vehicles from several manufacturers—and Rob was faced with some major decisions. The first came when another local dealer, who handles Volvos, Saabs, and Volkswagens, approached Rob about purchasing his dealership. More recently, the local Chrysler dealership got into difficulty and Rob bought them out. So, now, on the same lot, Rob sells the complete line of Pontiacs, the expensive Volvos, Saabs, Volkswagens, and the Chrysler products, including the popular Jeep line. Whitner Pontiac employs 83, including 23 full-time salespeople. Because of the diverse product line, there is considerable variation in the selling price of the vehicles. A top-of-the-line Volvo sells for more than twice the price of a Pontiac Grand Am. Rob would like you to develop some tables and charts that he could review monthly and would like you to report where the selling prices tend to cluster, where the variation is in the selling prices, and to note any trends. The data are on Connect, Data Sets, and Whitner Autoplex.
