Answer:
the answer is 7
Explanation:
Two steps
1. subtract the mean from each of the values and get the absolute values:
149 - 161 = -12, |-12| = 12. Do this to each value, and you will get 12, 8, 2, 5, 6 and 9.
2. Then add the values up and you will get 12 + 8 + 2 + 5 + 6 + 9 = 42
Then divide 42 by the number of values (essentially getting the mean of these numbers) so 42/6 = 7.
Thus, the final answer is 7.
