b. Is necessary to fit the multiple regression line to set of points
c. Must be adjusted for the number of independent variables
d. All of these options

Answer 1

a. Is the expected value of the dependent variable Y when all of the independent variables have the value zero

Step-by-step explanation:

• This regression is the extension of the simple linear regression and is used when we want to define the values of the variable based on the values of the two or more variables and constant terms in the regression analysis are the values at which the regression line crosses at the Y-axis.
