1. A simple linear regression model is an equation that describes the straight-line relationship between a dependent variable and an independent variable. T or F 2. The residual is the difference between the observed value of the dependent variable and the predicted value of the dependent variable. T or F 3. The experimental region is the range of the previously observed values of the dependent variable. T or F

When we estimate a linear multiple regression model (including a linear simple regression model), it appears that the calculation of the coefficient of determination, R2, for this model can be accomplished by using the squared sample correlation coefficient between the original values and the predicted values of the dependent variable of this model. Is this statement true? If yes, why? If not, why not? Please use either matrix algebra or algebra to support your reasoning.
