A regression equation that predicts the price of homes in thousands of dollars is = 24.6 + 0.055×1 – 3.6×2,where x2 is a dummy variable that represents whether the house is on a busy street or not.Here x2 = 1 means the house is on a busy street and x2 = 0 means it is not.From this we can conclude that on average homes that are on busy streets are worth $3600 more than homes that are not on busy streets.
