The Following Output Is for a Second-Order Polynomial Regression Model

question 129

True/False

The following output is for a second-order polynomial regression model where the independent variables are x and x² (x^2).Some of the output has been omitted. Considering the above information,it is clear that the second-order polynomial model will be a more effective regression model for explaining the variation in the y variable than would a linear regression model involving only one independent variable,x.
