Find the regression equation; unless the problem suggests otherwise, let the first variable be the independent (x) variable. Caution: When finding predicted values, be sure to follow the prediction procedure described in this section.
Refer to Data Set 7 of Appendix B and use the paired data consisting of temperature departures and precipitation departures from seasonal norms. What is the best predicted precipitation departure in a spring whose temperature was 0.9°C below the norm?
