    It is a little difficult to see the problem. I suggest you close this and just type it out.

    why not? seems you should know it or have access to it to do thses types of problems. i can write for you if you'd like but it might be better if you had it in a book

    sorry... don't want to discurage you but there seems to be some people here who just want answers and aren't really interested in learning. it just seems to me if you're doing regression you should have an idea of what's what, like xbar and s_x etc.
