Workers at a particular mining site receive an average of 35 days paid vacation which is lower than the national average. The manager of the plant is under pressure from a local union to increase this number. However, the manager does not want to increase the number of days off because that is costly and the mine is just barely making money. Instead he decides that he will fire 10 employees in such a way as to raise the average number of days off that are reported by his employees. To achieve this goal, should he fire the 10 employees that have the most number of days off, least number of days off, or those who have about the average number of days off? Explain your answer.

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.
The average of paid time off is the sum of the paid time off which is (T) of each employee divided by the number of employee (n).
