i. Multiple regression is used when two or more independent variables are used to predict a value of a single dependent variable. ii. The values of b₁, b_2, and b₃ in a multiple regression equation are called the net regression coefficients. They indicate the change in the predicted value for a unit change in one X when the other X variables are held constant. iii. Multiple regression analysis examines the relationship of several dependent variables on the independent variable. A) (i), (ii), and (iii) are all correct statements. B) (i) and (ii) are correct statements but not (iii). C) (i) and (iii) are correct statements but not (ii). D) (ii) and (iii) are correct statements but not (i). E) (i), (ii), and (iii) are all false statements.

Statement (i) correctly defines multiple regression, statement (ii) correctly describes the net regression coefficients, but statement (iii) incorrectly describes the relationship examined by multiple regression. Multiple regression analyzes the relationship between one dependent variable and multiple independent variables, not the other way around as stated in statement (iii).
