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
