2) Use the data in Problem 1 and develop a regression model to predict selling price based on the square footage and number of bedrooms. Use this to predict the selling price of a 2,000-square-foot house with 3 bedrooms. Compare this model with the models in Problem 1. Should the number of bedrooms be included in the model? Why or why not?
