Answer 1

38.9 and 40

Explanation:

Answer 2

`Mean = 38.9`
`Median = 40`

Explanation:

When you find mean, you must add all the numbers together then divide by the amount of numbers.

`10+31+36+36+38+42+47+48+49 + 52`

`==> 389`

There are 10 numbers.

`389 / 10`

`==> 38.9`

To find median, you have to either find the middle number or find the two numbers that makes it equal. Since this range set is even, we use the second option.

`(x + y ) / 2`

`38 + 42`

`==> 80`

Divide by 2

`80 / 2`

`==> 40`
