In a study of how chief executive officers (CEOs) spend their days, it was found that CEOs spend an average of about 19 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 100 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 16 17 24 15 21 24 25 20 18 23 17 25 22 19 20 24 19 12 16 13 17 18 22 24 16 23 12 22 20 17 18 16 21 13 22 21 22 17 14 23 19 13 18 23 22 25 16 24 25 17 19 19 22 22 18 22 15 25 25 22 21 13 24 15 12 25 22 23 16 22 19 23 19 12 21 Using a class interval size of 2, construct a Grouped Frequency Distribution Table (GFDT) What is the computed sample mean?
