Frank wants to know how many people live in each household in his town. he conducts a random survey of 10 people and asked how many people live in their household. his results are shown in the table

1.9

Step-by-step explanation:

The MAD is found by finding the mean, then finding how far each number is to the mean, then finding the mean of that.

The mean is: (1 + 8 + 3 + 1 + 3 + 3 + 7 + 5 + 1 + 3)/10 = 35/10 = 3.5

The distances of all of the numbers is (absolute value of the difference between 3.5 and the number) : 2.5, 4.5, 0.5, 2.5, 0.5, 0.5, 3.5, 1.5, 2.5, 0.5

The mean of those is: (2.5 + 4.5 + 0.5 + 2.5 + 0.5 + 0.5 + 3.5 + 1.5 + 2.5 + 0.5) /10 = 19/10 = 1.9
