You are a real estate broker who wants to compare property values in Glen Cove and Roslyn (which are located approximately 8 miles apart). In order to do so, you will analyze the data in GCResiyn, a file that includes samples of houses from Glen Cove and Roslyn. Making sure to include the dummy variable for location (Glen Cove or Roslyn), develop a regression model to predict appraised value, based on the land area of a property, the age of a house, and location. Be sure to determine whether any interaction terms need to be included in the model.
