Chapter 3, Problem 5P
Entrepreneur magazine ranks franchises. Among the factors that the magazine uses in its rankings are growth rate, number of locations, start-up costs, and financial stability. A recent ranking listed the top 20 U.S. franchises and the number of locations as follows:
These data can be found in the file Franchises. Create a PivotTable to summarize these data using classes 0–9,999, 10,000–19,999, 20,000–29,999, 30,000–39,999 to answer the following questions. (Hint: Use Number of U.S. Locations as the COLUMNS, and use Count of Number of U.S. Locations as the VALUES in the PivotTable.)
- a. How many franchises have between 0 and 9,999 locations?
- b. How many franchises have more than 30,000 locations?
