QUESTION 11In the context of a controlled experiment, consider the simple linear regression formulation Y = A0 + B1X + uj. Let the Y be the outcome, X the treatment levelwhen the treatment is binary, and uj contain all the additional determinants of the outcome. Then Po:O a.is the difference between the sample average outcome of the treatment group and the sample average outcome of the control group.bis the sample average in the control group.does not have an interpretation, since neither Y nor X are in differences.O d.is not quite accurate since it is actually the derivative of Y on X.O e. All of the above.Of. None of the above.QUESTION 12Assume that data are available on other characteristics of the subjects that are relevant to determining the randomized experimental outcome. Then notincluding these determinants explicitly results in:O a. the limited dependent variable model.b omitted variable bias.OC the multiple regression model.Od.Harge scale equilibrium effects.O e. All of the above.Of.None of the above.
