Compute the mean team operating income and the median team operating income, and explain the difference between the values of these statistics.

In the National Basketball Association (NBA) lockout of 2011, the owners of NBA teams wished to change the existing collective bargaining agreement with the NBA Players Association. The owners wanted a €œhard salary cap€ restricting the size of team payrolls. This would allow €œsmaller market teams€ having less revenue to be (1) financially profitable and (2) competitive (in terms of wins and losses) with the €œlarger market teams.€ The NBA owners also wanted the players to agree to take less than the 57 percent share of team revenues that they had been receiving. The players opposed these changes. Table 3.2 on the next page gives, for each NBA team, the team€™s 2009€“2010 revenue, player expenses (including benefits and bonuses), and operating income as given on the Forbes.com website on Octo-ber 26, 2011. Here, the operating income of a team is basically the team€™s profit (that is, the team€™s revenue minus the team€™s expenses including player expenses, arena expenses, etc.€”but not including some interest, depreciation, and tax expenses).
