Chapter 2, Problem 6P

In a study of how chief executive officers (CEOs) spend their days, it was found that CEOs spend an average of about 18 hours per week in meetings, not including conference calls, business meals, and public events. Shown here are the times spent per week in meetings (hours) for a sample of 25 CEOs:

1. a. What is the least amount of time a CEO spent per week in meetings in this sample? The highest?
2. b. Use a class width of 2 hours to prepare a frequency distribution and a percent frequency distribution for the data.
3. c. Prepare a histogram and comment on the shape of the distribution.
