Hello,
I didn't know where to put my question, but I think here is the best section for it.

The problem isn't that I can't solve it, I actually did but I don't understand the concept ! -- I don't remember anything from my high school stat and I didn't do college stat yet.
to be more specific in my question, what does the squire of the deviation mean? and how taking the sum of them give me the result I want?
