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.
