Identify a regression model that accurately predicts the sale price of a condominium unit. Several regression models have been tried. One regression model includes all independent variables (X1-X5) and two square terms (Floor 2 and Distance2). In addition to all the main effects and the two squared terms of Floor and Distance, we also explore two way interaction terms between Floor and View (X1*X3). Namely, identify the regression model for Y that include variables: X1-X5, X12, X22, (X1 * X3). For a condo at 5th Floor, 8-unit from elevator, Ocean View, End unit with the presence of furniture, what will be the point estimate of price
