du/courses/83410/quizzes/253326/take Use the following information to answer Questions 1-8. Consider the following model In(wage) Bo + Biezper + Batenure + u where wage is the monthly salary in dollars, exper is the number of years in the work force. tenure is the number of years at the current job. The OLS estimated equation is In (wage) 5.89 +0.0182 x exper+0.0022 x tenure, with R2 0.066.

Question 7 Suppose the original model in this question given by In(wage) Bo + Biezper + Batenure + u. - satisfies MLR 1-5. It is known, in the data, exper and tenure are positively correlated. Suppose you drop the regressor tenure, and run the regression In(wage) Bo + Biezper+u.. - (a) In this case, which assumption is the most likely to be violated? [Select] (b) Can the OLS estimator be unbiased? [Select] 10 pts (c) If the OLS estimator is biased, what is the likely direction of the bias? [Select]

Question 7 10 pts Suppose the original model in this question given by In(wage) Bo + Biezper + Batenure + u. satisfies MLR 1-5. It is known, in the data, exper and tenure are positively correlated. Suppose you drop the regressor tenure, and run the regression In(wage) Bo + Biezper+u.. (a) In this case, which assumption is the most likely to be violated? [Select] (b) Can the OLS estimator be unbiased [Select] unbiased biased (c) If the OLS estimator is biased, what is the key direction of the dias? [Select]

Question 7 Suppose the original model in this question given by In(wage) Bo + Biexper+ Batenure + u. satisfies MLR 1-5. It is known, in the data, exper and tenure are positively correlated. Suppose. you drop the regressor tenure, and run the regression In(wage) Bo + Biexper+u. (a) In this case, which assumption is the most likely to be violated? Select ] = MLR1 MLR2 MLR3 MLR4 MLR5 None of the assumptions Select] unbiased? blased 10 pts sed, what is the likely direction of the bias?

Suppose the original model in this question given by In(wage) Bo + Biexper+ Batenure + u, satisfies MLR 1-5. It is known, in the data, exper and tenure are positively correlated. Suppose you drop the regressor tenure, and run the regression = In(wage) Bo + B₁exper+u. (a) In this case, which assumption is the most likely to be violated? [Select] - (b) Can the OLS estimator be unbiased? blased (c) If the OLS estimator is biased, what is the likely direction of the bias? Select] unbiased biased downwards biased upwards
