The answer is 6.2

Step-by-step explanation:

Explanation: x = [(∑xi)/n] = [(12 + 3 + 18 + 17 + 4 + 9 + 17 + 19 + 20 + 15 + 8 + 17 + 2 + 3 + 16 + 11 + 3 + 1 + 0 + 5)/20] ∴ x = 10 Mean deviation = [(∑|xi – x|)/n] = [(2 + 7 + 8 + 7 + 6 + 1 + 7 + 9 + 10 + 5 + 2 + 7 + 8 + 7 + 6 + 1 + 7 + 9 + 10 + 5)/20] = (124/20) = 6.2.
