6-18.

How does the mean of the new books compare to the mean of the original group?

You are adding one number to each end.

You are not making any numbers appear more often.

Your largest number is changing from 35 to 64.

Before: mean = 25, median = 26, mode = 35, range = 23.

Remember to calculate the central tendencies after the new books are added.
