Question

Hammie is in 6^th grade and weighs 106 pounds. His quadruplet sisters are tiny babies and weigh 5, 5, 6, and 8 pounds. Which is greater, the average (mean) weight of these five children or the median weight, and by how many pounds?

Accepted Answer

Listing the elements from least to greatest, we have (5, 5, 6, 8, 106), we see that the median weight is 6 pounds. The average weight of the five kids is 5+5+6+8+1065 = 1305 = 26. Hence,26-6=average, by 20.
