   True

2. False

QUESTION 2 Choose the correct interpretation for the coefficient in the the following multiple regression model: ni = + B1x1 + @2x2 , represents the change in the mean value of the dependent variable y that corresponds to a one-unit increase in all the independent variables included in the model. , represents the change in the mean value of the dependent variable y that corresponds to one-unit increase in the independent variable X1, holding the values of all other independent variables in the model constant. , represents the change in the mean value of the dependent variable y that corresponds to a one-unit increase in the independent variable X1
