Suppose that you are estimating the simple regression model Y; = B1 + B2 X; + ui, and in your sample, the dependent variable and regressor are negatively correlated. %3D Select one: a. The OLS estimator of the slope, b2 < 0. O b. The OLS estimator of the slope, b2 > 0. O c. The OLS estimator of the intercept, b1 > 0. O d. The sign of the OLS slope estimator depends of the variance of X and Y in the sample.
