Answer:  A. The mean absolute deviation is 4

Step-by-step explanation:

Mean absolute deviation (MAD) is found by finding the absolute value of difference between each number in set and mean, adding them together, then dividing by total numbers in set.

Differences

72-62= 10

72-73= 1

72-74= 2

72-75= -3

72-76= -4

add the absolute values...

10+1+2+3+4=20

divide by 5 because that is how many numbers in set...

20/5=4
