Question

Kenneth surveyed 1000 people about the change in the balance of their bank accounts over the course of a week.

He recorded his data and calculated a mean and a median. Then, he realized that what he thought was the
maximum value in his data set should have been a negative value, making it the new minimum value in his data
set.
Which statement most likely describes the mean and the median of his new, corrected data set?
A Only the mean will be lower; the median must remain the same.
