I the Values of B1, B2 and B3 in a Multiple

question 35

Multiple Choice

i. The values of b1, b2 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.
ii. Multiple regression analysis examines the relationship of several dependent variables on the independent variable.
Iii) A multiple regression equation defines the relationship between the dependent variable and the independent variables in the form of an equation.

• 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) All statements are false.
