Question

The following data shows the weight, in pounds, of 6 bags:

6, 4, 8, 7, 8, 9

What is the value of the mean absolute deviation of the weight of the bags, and what does it represent about the weight of a bag?
1.8 pounds; on average, weight of a bag varies 1.8 pounds from the mean of 7 pounds
1.3 pounds; on average, weight of a bag varies 1.3 pounds from the mean of 7 pounds
1.3 pounds; the weight of 50% of the bags is greater than 1.3 pounds
1.8 pounds; the weight of 50% of the bags is greater than 1.8 pounds

Answer 1

I got 7 pounds

Answer 2

To find the average, add up all the numbers and divide them from one another. 7 pounds is the average

Answer 3

i got 42 how do i divide it from one another?

Answer 4

Answer 5

Divide by the number of numbers, meaning divide 42 by how many bags are in the data set. 7 pounds is the average weight of the bags.

Answer 6

To find the mean deviation, you have to find the distance of each number to the value or 7.

Answer 7

of*

Answer 8

i got 7 i know that 42 divided by 6 = 7

Answer 9

Yes, and the problem is looking for the mean deviation.
Find the distance from all the numbers to 7.

Answer 10

how do i do that?

Answer 11

Answer 12

Subtract the mean from each value, ignore minus signs if there are in the solution.
So,
7 - 6
7 - 4
7 - 8
7 - 7
7 - 8
7 - 9

After you've received all the distances, add them all up and you'll receive the deviation.

Answer 13

1, 3, -1, 0, -1, -2

Answer 14

so 1.3?

Answer 15

Ignore the negative signs, and then add them and divide by 7 to get the deviation.

Answer 16

Divide by 6*

Answer 17

and yes, 1.3

Answer 18

can you help with one more?
