.

Answer 1

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

the answer is: $ 7.2
