If all numbers in a set are less than the average, is this possible?
Think back to the contradiction method we discussed.
Given the numbers 1, 2, 4, 5, 8, demonstrate that at least one number is greater than the average, then calculate the average.
First, compute the average correctly before identifying the numbers altering the interpretation.
