Question

Quinn mailed four postcards that each cost $0.25, five letters that each cost $0.44, two large envelopes that each cost $0.80, and one small package for $5.10. Which cost on the list of mailing fees on Quinn’s receipt would skew the mean?

the cost of a postcard

the cost of a letter

the cost of a large envelope

the cost of the small package

Answer 1

The mean is the average price of all the items. The term "skew the mean" means to shift away from the average value. The postcards, letters, and envelopes all cost less than a dollar. This would suggest the mean would be less than a dollar. However, the box costs $5.10 - this is going to pull the average so that it is greater than a dollar. The box will "skew the mean."
