Most team members earned commissions considerably lower than the mean of 690 point 1 1 dollars.
C
One or more team members earned a significantly lower commission, causing the mean to decrease.
D
The commissions are uniformly distributed among the team members.
Explanation
The mean, $690.11, is lower than the median, $700, which suggests that relatively low commissions are pulling the mean downward. In particular, the $500 commission is well below the rest of the values and lowers the average. So the true statement is that one or more team members earned a significantly lower commission, causing the mean to decrease.
