In the Context of a Controlled Experiment,consider the Simple Linear

Question 23

Multiple Choice

In the context of a controlled experiment,consider the simple linear regression formulation Yi = β0 + β1Xi + ui.Let the Yi be the outcome,Xi the treatment level,and ui contain all the additional determinants of the outcome.Then


A) the OLS estimator of the slope will be inconsistent in the case of a randomly assigned Xi since there are omitted variables present.
B) Xi and ui will be independently distributed if the Xi be are randomly assigned.
C) β0 represents the causal effect of X on Y when X is zero.
D) E(Y In the context of a controlled experiment,consider the simple linear regression formulation Yi = β0 + β1Xi + ui.Let the Yi be the outcome,Xi the treatment level,and ui contain all the additional determinants of the outcome.Then A) the OLS estimator of the slope will be inconsistent in the case of a randomly assigned Xi since there are omitted variables present. B) Xi and ui will be independently distributed if the Xi be are randomly assigned. C) β0 represents the causal effect of X on Y when X is zero. D) E(Y X = 0) is the expected value for the treatment group. X = 0) is the expected value for the treatment group.
