Ok, so I am thoroughly confused atm. Right now I am trying to do three things.

Calculate SS Total, and the explained sum of squared variation for SSR.

Ok so I had the outputs given to me of

Sum x = 30

Sum x squared = 104

Sum of y = 40

Sum of y squared - 178

Sum of x times y = 134

I used that data to solve and get the following

SSxy = 14

SSxx = 14

b1 = 1

ybar = 4

xbar = 3

b0 = 1

yhat = 1 + 1x

Ok so based on this the sqares regression line is 1+x

so y intercept is 1 and slope is 1

I calculated sse to be 9...

When I try and calculate sst which is xbar1-xbar

I get 10(30-3)^2 = 7290

Im pretty sure this number is wrong. Can anyone tell me what I am doing wrong?
