Refer to the temperature and precipitation data in Data Set 4 of Appendix B. Let the dependent variable be AVTEMP, and let the independent variables be those given in the exercise. (The data sets are already stored on the data disk and STATDISK.) Use software such as Excel, Minitab, or STATDISK to answer these questions:
Construct a model in which AVPRECIP and AVSNOW are used to predict AVTEMP. If a city has average precipitation of 900 mm per year and average snowfall of 225 cm per year, what is the city's predicted average temperature, accurate to 1 decimal?
