A national single-family homes and condominium-townhousesThe accompanying provides information on the price, lot , and type of home for closings during one monthComplete parts a through c.
during one month. Cornpleto ports a through c. Cick the icon to view the house sales data. a. Devolop a muntiple regression model for sales price as a function of lot cost and typo of horne wheut any interaction term. Creole a dummy variable named "Townheuse", where it is equal to 1 when Type = "Towrhouse" and 0 otherwise. Determine the coeffcients of the regression equation. Sales Price =+1i Lot Cost +i Townhouse (Round the constant and coefficient of Townhouse to the nearest integer as needed. Round all other values io two decinal places as noeded). b. Determine if an interaction exists between lot cost and type of heme and find the best model, Use =0.1ms the level of significance. First detemine whether an infernction mists. Select the correct cholce below and, if nocessary, fit in the answer box to complete your choice. A. An interaction exists because the p-value of the variable Lot Cost. Townhouse is which is less than a. (Type an integer or a decimal rounded to three decimal places as neodod.) B. An interaction exists because the p-value of the variable Lot Cost is, which is greater than a. (Type an integer or a decimal rounded to three decimat places as needed.) c. An interaction exists begaise the p-value of the variabio Townhouse is which is greater than a. (Type an inleger a docimal rounded to three decimal places as needed.) D. No interaction exists because the p-value is less then a for all of the independent variables. Now identify the best model and determine the coeflionts of the regression equation. select the correct choice below and sth in the answer boxes to complete your cheicen.
