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?
