The class with the greatest mean sales in a spring fundraiser will win a prize. The mean for Eric's class is $148. The mean for Natalia's class is $152. Natalia's sales total $150. If Natalia moves to Eric's class, the mean for each class increases. Explain why?

    150 is less than the mean for Natalia's class. So, if that score is removed, the mean rises.

    Similarly, since 150 is greater than the mean for Eric's class, if that score is added, the mean rises.
