CEO Time in Meetings. The London School of Economics and the Harvard Business School have conducted studies of how chief executive officers (CEOs) spend their time. These studies have found that CEOs spend many hours per week in meetings that include conference calls, business meals, and public events. Suppose that the data below show the time spent per week in meetings (hours) for a sample of 25 CEOs. 14 15 18 23 15 19 20 13 15 23 23 21 15 20 21 16 15 18 18 19 19 22 23 21 12 a) What is the least amount of time spent per week on meetings? The highest? b) Use a class width of two hours to prepare a frequency distribution and a percent frequency distribution for the data. c) Prepare a histogram and comment on the shape of the distribution
