(a) Predict the distance a golf ball will travel if the club-head speed is 100 mph b) Suppose the observed distance a golf ball traveled when the club-head speed was 100 mph was 265 yards. What is the residual? (a) The golf ball will travel yards. (Round to the nearest tenth as needed.)

The least-squares regression line minimizes the sum of squared residuals. The leastsquares regression line always contains the point (0,0). The sign of the linear correlation coefcient, r, and the sign of the slope of the least-squares regression line, [71, are the same. The least-squares regression line maximizes the sum of squared residuals. WP??? 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. 3" The predicted value of y, )7, is an estimate of the mean value of the explanatory variable for that particular value of the response variable.
