5. Use software such as STATDISK, Minitab, or Excel to find the multiple regression equation of the form , where the response variable y represents cost, x1 represents electricity consumption in kWh, and x2 represents average daily temperature. Also identify the value of the multiple coefficient of determination R2, the adjusted R2, and the P-value representing the overall significance of the multiple regression equation. Can the regression equation be used to predict cost? Are either of the regression equations from Exercises 3 and 4 better?
