Answer 1

TRUST ME I DID THE MATH ON PAPER, ITS 7.2!!!

Explanation:

Answer 2

The average distance from the mean is:

$ 7.2

Explanation:

We are given data points as:

$7, $20 , $9 , $35 , $12 , $15 , $7 , $10 , $20 , $25 , $7 , $20 , $9 , $35 , $12 , $15 , $7 , $10 , $20 , $25

The mean of the data set is:

Now we are asked to find the average distance from the mean or MAD of the data.

The absolute difference of each data point from mean is calculated as follows:

|7-16|=9

|20-16|=4

|9-16|=7

|35-16|=19

|12-16|=4

|15-16|=1

|7-16|=9

|10-16|=6

|20-16|=4

|25-16|=9

|7-16|=9

|20-16|=4

|9-16|=7

|35-16|=19

|12-16|=4

|15-16|=1

|7-16|=9

|10-16|=6

|20-16|=4

|25-16|=9

Hence, the mean of these absolute difference is calculated by:

`MAD=(9+4+7+19+4+1+9+6+4+9+9+4+7+19+4+1+9+6+4+9)/(20)\\\\\\MAD=(144)/(20)\\\\\\MAD=7.2`

Hence, the answer is:

$ 7.2
