Answer:

the answer is D. 1.52

Step-by-step explanation:

you want to add all the numbers then divide by 10

15 + 15 + 17 + 18 + 18 + 18 + 19 + 20 + 20 + 21

                             10

then you find the difference between the mean and data point

Data point = 15    15    17    18     18     18     19    20    20     21

Mean Diff  = 3.1   3.1     1.1    0.1   0.1   0.1    .9      1.9    1.9    2.9

then add the differences

3.1 + 3.1 + 1.1  + 0.1 + 0.1  +  0.1 + .9 + 1.9 + 1.9  + 2.9 and divide by 10

                                    10

absolute deviation is 1.52 wings.
