Use software such as Excel, Minitab, or STATDISK to find the multiple regression equation of the form = bQ + blxl + b2x2 + b3x3, where the dependent variable y represents consumption, x, represents price, x-, represents income, and x3 represents 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 ice cream consumption? Are any of the equations from Exercises 1-3 better?
