A real estate analyst has developed a multiple regression line, y = 60 + 0.068 x1 – 2.5 x2, to predict the market price of a home (in $1,000s), using two independent variables, x1 = the total number of square feet of living space, and x2 = the age of the house in years. With this regression model, what is the predicted price of a 10-year old home with 2,500 square feet of living space? Dependent / Response Variable Independent...
