This table summarizes the number of cases (a case has 24 bottles or cans) of different types of soft drinks sold in the United States in 2004. (From Beverage Digest, March 4, 2005.)

(a) Describe your impression of the underlying data table. Do you think that it has a row for every case of soft drinks that was sold?
(b) Prepare a chart of these data to be used in a presentation. The plot should emphasize the share of the market held by the different brands.
(c) Prepare a chart of these data that compares the share of the market held by each of the three companies. Is this chart different from the chart used in part (b)? If not, explain how you could use the chart in part (a).
(d) Prepare a chart that contrasts the amounts of diet and regular soft drinks sold.
