Develop a dummy variable that will account for whether the refrigerator has the thru-the-door ice and water feature. Code the dummy
variable with a value of 1 if the refrigerator has the thru-the-door ice and water feature and 0 otherwise. Use this dummy variable to
develop the estimated multiple regression equation to show how list price is related to cubic feet and the thru-the-door ice and water
feature.
Be sure to state the model and interpret the coefficients.
