Mean:

Add all the numbers:

13 + 17 + 15 + 18 + 21 + 13 + 20 + = 16.7
16.7 + 3.7 = 20.4

Mean = 20.4

Median:

Order the numbers:

13, 13, 15, 17, 18, 20, 21

The median, or middle number is 17.
17 + 3.7 = 20.7

Median = 20.7

Mode:

The number that repeats the most is 13.
13 + 3.7 = 16.7

Mode = 16.7

Range:

Highest Number = 21

Lowest Number = 13

21 - 13 = 8

Range = 8

The answer choice that matches is choice A.

Step-by-step explanation:

Answer A: Subtract 9 from both sides
