Answer 6

I am getting an extra number. But I don't know where I am getting it from:

I am supposed to get seven integers, but I am getting eight.

Answer 8

\[\large MAD=\frac{1}{n}\sum_{i=1}^{n}|x _{i}-\bar{x}|\]
where n is the number of observed values, x-bar is the mean of the observed values, and x suffix i are the individual values.

Answer 9

Okay I got it...
