    E[MSE] simple linear regression

    Hi All- I am trying to figure out how to prove that MSE = SSE/n-2 is an unbiased estimator of sigma^2 in simple linear regression. I have that (1/(n-2))E{SUM[Yi^2-2Yib1Xi-2boYi+bo^2+b1^2Xi^2]} Are bo and b1 random variables? Am I going about this the right way? Thanks!
