Document Summary
The regression equation is y = 0 + 1x, where y is the predicted average y-value for all observations with the same x-value (x). The coe cients 0, 1 are found using the formulas. 1. 145 and 0 = y 1x 135 1. 145 24 = 107. 52, so the regression equation is. This is the same as the formula that we get using the regression method": Y = y + rxy x x. The r. m. s. error of regression is the number (cid:113) Include a margin of error (a plus/minus" number) with your estimate. The predicted blood pressure for a 30-year old man who smokes 30 cigarettes/day is the average blood pressure of all men age 20-40 who smoke 30 cigarettes/day, which we estimate using the regression equation: The margin of error is given by the ser, so that the predicted blood pressure for such a man is.
