Question 3 Suppose the random variable (y, X) satisfy Ey|X) = XB. 1. Show that this is equivalent to assumption 1 and assumption 2 in the classic linear regression model. 2. Show that the OLS estimator b for B is unbiased. 3. Based on 1 and 2, show that the OLS estimator is estimating the conditional mean function under classic linear regression model assumptions by showing E(Xb|X) = X B = E(y|X)
