Answer 2

Answer:

The cost of a small package on Quinn's receipt would skew the mean.

Skewing:

• Skewing refers to the shifting or deviation from a symmetric distribution.
• If the distribution curve shifts to the left or right, it is said to be skewed.
• It can also be said as the lack of symmetry.
• There are two types of skewness: positive or right-skewed and negative or left-skewed.

Step-by-step explanation:

Step 1:

One postcard costs $0.25

Therefore, four postcards will cost (0.25×4) = $1

Step 2:

One letter costs $0.44

Therefore, five letters will cost (0.44×5) = $2.2

Step 3:

One large envelope costs $0.80

Therefore, two large envelopes will cost (0.80×2) = $1.60

Step 4:

The mean of the four postcards, five letters, and two large envelopes is:

$Mean=\frac{1+2.2+1.6}{11}$

$Mean=\frac{4.8}{11}$

$Mean = 0.436$

Step 5:

The mean of the four postcards, five letters, two large envelopes, and one small package is:

$Mean = \frac{1+2.2+1.6+5.10}{12}$

$Mean = \frac{9.9}{12}$

$Mean = 0.825$

The mean is getting doubled with the addition of one small package.

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