Question

4, 2, 4, 1, 8, 9, 7, 5, 2, 8

By how much would the range decrease if the number 7 replaced the number 9 in the set?

Answer 1

0

Explanation:

The range is the difference between the lowest and highest values. Since 9 is still the highest value, the range would not change by any amount by replacing 7 with 9.
