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? a. the cost of a postcard b. the cost of a letter c. the cost of a large envelope d. the cost of the small package

Option D is the correct choice.

Step by step explanation:  

We have been given that 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.

Since we know that mean is the average of numbers. Outliers of a data set affect mean. An outlier with very small value decreases mean of a data set while a large value outlier increases mean of data set.

We can see that for our given data cost of mailing one small package is $5.10, which has huge difference from other mailing amounts. It will increase mean of our data set.

Therefore, cost of the small package on the list of mailing fees on Quinn’s receipt would skew the mean.
