At the end of 2011 Chrysler Motors was trying to decide whether or not to discontinue production of a Jeep model introduced in 2002— the Jeep Liberty. Although Liberty sales had generally declined since 2007 with the cancellation of one Jeep model and the introduction of three new Jeep models, Liberty sales had continued to be good ( and the Liberty name had retained a positive image) at some Jeep dealerships. Suppose that the owner of one such dealership in Cincinnati, Ohio, wished to present Chrysler with evidence that Liberty sales were still an important part of total sales at his dealership. To do this, the owner decided to compare his dealership’s Liberty sales in 2011 with those in 2006. Recently summarized sales data show that in 2011 the owner’s dealer-ship sold 30 Jeep Compasses, 50 Jeep Grand Cherokees, 45 Jeep Libertys, 40 Jeep Patriots, 28 Jeep Wranglers, and 35 Jeep Wrangler Unlimiteds. Such summarized sales data were not available for 2006, but raw sales data were found. Denoting the four Jeep models sold in 2006 (Commander, Grand Cherokee, Liberty, and Wrangler) as C, G, L, and W, these raw sales data are shown in Table 2.22. Construct percent bar charts of (1) Jeep sales in 2011 and (2) Jeep sales in 2006. Compare the charts and write a short report supporting the owner’s position that in 2011 Liberty sales were still an important part of sales at his dealership.
