Problem 4 Verify that for the multiple linear regression model Y : X [3+6 with one predictor variable, the least square estimate of ,8 using the matrix form gives the same result as in SLR. Then use the matrix form to derive the variance-covariance matrix of )6 and verify the variances VarUBo) and Var(,81] are the same as their counterparts derived in SLR
