Use the data set in WAGE2 for this problem. As usual, be sure all of the following regressions contain
an intercept.
(i) Run a simple regression of $I Q$ on educ to obtain the slope coefficient, say, $\tilde{\delta}_{1}$
(ii) Run the simple regression of log(wage) on educ, and obtain the slope coefficient, $\widetilde{\beta}_{1}$
(iii) Run the multiple regression of log(wage) on educ and $I Q,$ and obtain the slope coefficients,
$\hat{\beta}_{1}$ and $\hat{\beta}_{2},$ respectively.
(iv) Verify that $\tilde{\beta}_{1}=\hat{\beta}_{1}+\hat{\beta}_{2} \tilde{\delta}_{1}$.
