Hey guys just looking for help with this question dealing with population variance.

I don't quite know how to write this problem down here, so I'll just do it in paint and post up a link.

Thanks, it would be helpful if you could explain it to me through paint also, as I don't really understand math displayed on a computer. I just don't know how to proceed on the question, and i don't even know what exactly it is asking me to do.

Your equality is not true. The mean is missing an exponent of 2. See below (by the way, this is "math displayed on a computer", and I'm not quite sure how this is worse than "numbers by paint"(Wink)):

Oops sorry I edited it, I still don't know how to solve it though. I don't think it's asking to change from one form to another. Your solution didn't have the substituted version of mu. Still really confused.

I think this is the question it's asking, imgur: the simple image sharer. Still not 100% sure though.
