What is the strength of the relationship?
Using the equation, predict the price of a Coop Apartment with 2640 sq feet, 2 bedrooms and is 2 years old.
Interpret b3 in your equation from part c
predicted price is 142939.6
interlretation of b3 is -1712
Coefficient b3 (beta3) is average change in y (selling price) for one unit change in x3 (age of conda) provided we hold x1 and X2 fixed.
