Interpretations A regression performed to predict the selling price of houses found the equation
where Price is in dollars, Area is in square feet, Lotsize is in square feet, and Age is in years. The R2 is 92%. One of the interpretations below is correct. Which is it? Explain what’s wrong with the others.
- a) Each year a house Ages it is worth $6543 less.
- b) Every extra square foot of Area is associated with an additional $35.30 in average price, for houses with a given Lotsize and Age.
- c) Every dollar in price means Lotsize increases 0.718 square feet.
- d) This model fits 92% of the data points exactly.
