Question: Which of the following statement(s) is/are true?
I. In linear regression, the regression equation contains one independent variable and one dependent variable.
II. In linear regression, the regression equation is written as y′ = a + bx.
III. In multiple regression, there can be several independent variables and one dependent variable.
IV. In multiple regression, the regression equation is written as y′ = a + b1x1 + b2x2 +...+ bkxk.


A ) I, II and III only
B ) I and IV only
C ) II and III only
D ) all are correct

Steps to derive

1 In simple linear regression, the regression equation contains one independent variable x and one dependent variable y′.

2 In simple linear regression, the regression equation is written as y′ = a + bx, where a is the y′ - intercept and b is the slope of the line.

3 In multiple regression, there are several independent variables and one dependent variable.

4 In multiple regression, the regression equation is written as y′ = a + b1x1 + b2x2 + ...+ bkxk, where x1, x2, x3, ..., xk are the independent variables.

5 So, all the statements are corect.



Hence the right answer is Option D
