True
Explanation:
PRF specifies the relationship (in the population) between the mean (average) value of the dependent variable (Y) corresponding to each value of the independent variable (X). This relationship may be specified algebraically as [tex]E(Y| X_i ) = B_1 + B_2X_i[/tex]. Graphically, the population regression line is a line that passes through the conditional means of Y. SRF specifies the relationship (in the sample) between the [tex]Y_i[/tex] , estimator of [tex]E(Y| X_i )[/tex], or the estimator of the population conditional mean, and its primary determinant X. Algebraically, it may be written as [tex]Y_I = b_1 + b_2X_i[/tex]
