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 point)

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

1.3 pounds; on average, weight of a bag varies 1.3 pounds from the mean of 7 pounds

Step-by-step explanation:

the mean absolute deviation is 1.3 and the mean is 7. i just took this test today, hoped this helped:)

i think c. but don't trust it.

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
