Which statement best compares the mean and median of the new data set to the mean and median of the original data set?
The mean of the new data set is equal to the mean of the original data set, and the median of the new data set is equal to the median of the original data set.

C
The mean of the new data set is less than the mean of the original data set, and the median of the new data set is equal to the median of the original data set.
