Suppose that you fit a linear regression model with including three parameters B = (Bo. B1. B2). You calculate the variance-covariance matrix of the least squares estimators and get 0.73 -0.2 -0.1 -0.2 1.21 0.3 -0.1 0.3 0.50 a) Based on this, what is the standard error of 3₁? b) What is the variance of Bo + B₂?
