Hello GRians. I need your help! I have a stats problem I can't figure out because...Well...I suck at stats. It's actually for my wife, for her stats 2 class. The only class she needs to get her bachelors degree and it sure is making her feel as though she'll never graduate lol. She was going to see a tutor today but the campus closed early for some unannounced reason. Anyways, here's the problem... I'm not expecting someone to do all of this but...Maybe just help break it down so it's a little bit simpler or show the formula and we can maybe go from there. I don't know...This is just all sorts of pain in the ass.
