Answer:

1.178

Step-by-step explanation:

(for Jamal)

5 x 2 = 10

6 x 3 = 18

7 x 2 = 14

8 x 1 = 8

10 x 1 = 10

Mean: 10 + 18 + 14 + 8 + 10 = 60/9 = 6.6

6.6 - 5 = 1.6 x 2 = 3.2

6.6 - 6 = 0.6 x 3 = 1.8

7 - 6.6 = 0.4 x 2 = 0.8

8 - 6.6 = 1.4

10 - 6.6 = 3.4

Mean Absolute Deviation: 3.2 + 1.8 + 0.8 + 1.4 + 3.4 = 10.6/9 = 1.178
