Okay, this chapter is wearing me out. I am not getting anything of all this. Let's start from a basic thing.

It says "compute SSr and SSE and (s_e)^2 and the coefficient of determination, given the following statisics computed form a random sample of pairs od X and Y observations (let's take just one)

Sum from i=1 to n of (y_i - y)^2 = 100,000

r^2 = 0.50

n= 52

No clue no clue..

Is there anybody who can explain me the simple regression. I cannot see the point of all this. Please. Thank you.
