In a study of how chief executive officers (CEOs) spend their days, it was found thatCEOs spend an average of about 18 hours per week in meetings, not including conferencecalls, business meals, and public events. Shown here are the times spent per week in meetings(hours) for a sample of 25 CEOs:14 15 18 23 1519 20 13 15 2323 21 15 20 2116 15 18 18 1919 22 23 21 12a. What is the least amount of time a CEO spent per week on meetings in this sample?The highest?b. Use a class width of 2 hours to prepare a frequency distribution and a percent frequencydistribution for the data.c. Prepare a histogram and comment on the shape of the distribution.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
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
(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

a. What is the least amount of time a CEO spent per week on meetings in this sample?
The highest?
b. Use a class width of 2 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.
