Question

A car company used the data in the table and advertised that the average mileage for all the car models it makes is 26 miles per gallon.

Why did the company use mean to report the mileage of its cars?

Mileage for All Car Models
Mileage (miles per gallon)
57
17
14
16


A.
Using the mode would show a greater mileage than the mean.

B.
The median would show a greater mileage than the mean.

C.
The mean shows a greater mileage than the median would.

D.
The mean is the most accurate measure of the mileage of the car models.

Answer 1

Well, what is a mean?

Answer 2

idk

Answer 3

Okay, Mean = Average
Do you know what an average is? :)

Answer 4

\[yes\]

Answer 5

Perfect! You get an average by adding all the numbers you're given, and then dividing the sum by how many numbers you have. In your case:
57 +17+14+16 = 104
104/4 = 26

(Just to make sure we're clear!)
Now, why might a car dealer use the average?

Answer 7

Answer 8

Answer 9

haha yes, but from out of the options you have.. :P

Answer 10

If the car dealer said "ALL of my cars run at 57" that wouldn't be accurate! Nor would it be accurate if he said they all run at 14. Getting the average makes it the most _accurate_ because it's an estimate

Answer 11
