(a) Calculate the regression line of gas consumption on average outside temperature. (b) Evaluate the residuals for the points where x = 3.0° and x = 7.8 5°C (c) Find an estimate for the weekly gas consumption when the outside temp is 5°C (a) equation is y = - 0.404x + 7.035 (b) Residual x =3 Residual x =7.8 (c) Predict y when x = 5 y = - 0.404x 5 + 7.035 = 5.02
