Professional athletes are threatening to strike because they claim that they are underpaid. The team owners have released a statement that says, in part, “The average salary for players was $1.2 million last year.” The players counter by issuing their own statement that says, in part, “The typical player earned only $753,000 last year.” Is either side necessarily lying? If you were a sports reporter, what questions would you ask about these statistics?

A company has 30 employees, including a director. The lowest salary among the 30 employees is $22,000. The director’s salary is $180,000, which is more than twice as much as anyone else’s salary. Decide for each of the following statements about the 30 salaries whether it is true, false, or you cannot tell on the basis of the information at hand. • The median salary is below $60,000.• The average salary is below $60,000.• If all salaries are increased by $1,000, that adds $1,000 to the average.• If the director’s salary is doubled, and all other salaries remain the same, that increases the average salary.• If the director’s salary is doubled, and all other salaries remain the same, that increases the median salary.• The standard deviation of the salaries is larger than $180,000
