Which of the following is true of the leastsquares regression line y 2 b1): + b0? Select all that apply. D A. The leastsquares regression line always contains the point (ii). [I B. The least-squares regression line maximizes the sum of squared residuals. D C. The predicted value of y, y, is an estimate of the mean value of the explanatory van'able for that particular value of the response variable. [I D. The sign of the linear correlation coefcient, rr and the sign of the slope of the leastsquares regression line, b1, are the same. [I E. The leastsquares regression line minimizes the sum of squared residuals. D F- The predicted value of y, y, is an estimate of the mean value of the response variable for that particular value of the explanatory variable. [I G. The leastsquares regression line always contains the point (0,0)
