Consider the regression model Y: = 30 + lei + ui . The interpretation of the slope coefficient of this model can be written as: O A. A one unit change in X is associated with a one unit change in Y O B. A one unit change in X is associated with B1 unit change in Y O C. A BO unit change in X is associated with one unit change in Y O D. A one unit change in X is associated with BO unit change in Y Which of the following statements is true about the central limit theorem? O A. It assumes that the sample mean 7 is a consistent estimator of the population mean ,uY O B, It only holds in the presence ofthe law of large numbers. O C. It states conditions under which a variable involving the sum of Y1, ..., Yn over i.i.d. variables becomes the Student tdistribution O D. It states conditions under which a variable involving the sum of Y1, ..., Yn over i.i.d. variables becomes the standard normal distribution Which of the following options is the proper formula for the standard error of Y, shown as SE (Y) = OF O A. SY 1 O B. ( n ) ( Yi - Y ) 2 Sy O C. Vn Sy 2 OD. Vn
