Answer: 2
Step-by-step explanation:
From the question, we are informed that a basketball team played six games and that in those games, the team won by 9 points, lost by 18, won by 8, won by 11, lost by 3, and won by 5.
Thee mean difference in game scores over the six games will be calculated as the summation of the scores divided by 6. This. Will be:
= [9 + (-18) + 8 + 11 + (-3) + 5]/6
= 12/6
