He is making you do least-squares regression by hand?

Excel can do it in a flash. Get help at an excel site on how to set up regression calculations.

Friend at work gave me some problems to solve …
Why? ;)

So, Danni, where are you stuck? Somebody has calculated the summations ∑xi and ∑yi. Was that you? Or, do you need help understanding the sigma (∑) notation?
