Step-by-step explanation:
<u>Rule</u>
- Subtract the 2nd number from the first to obtain the first digit(s) of the answer.
- Add the 2nd number to the 1st to obtain the last digit(s) of the answer.
5 - 3 = 2
5 + 3 = 8
Therefore: 28
9 - 1 = 8
9 + 1 = 10
Therefore: 810
8 - 7 = 1
8 + 7 = 15
Therefore: 115
6 - 2 = 4
6 + 2 = 8
Therefore: 48
7 - 5 = 2
7 + 5 = 12
Therefore: 212

The mean is:

The mean absolute deviation is:

And the population standard deviation is:

In this case, our set has 5 elements, and the set is:
{2, 4, 6, 9, 14}
The mean of this set is:

The mean absolute deviation is:

And the population standard deviation is:
