I have a question in a book that i canot seem to begin to understand. my problem is trying to understand the way to solve on excel.
the problem is stated as such ;a real estate executive has created a regression model,price of the house is Y and square footage is X . the model is y(hat)=13,373 +36.65X the coefficient correlation for the model is0.63.
they ask , use the model to predictthe selling price of a house that is (a)1,860 sq feet,(b)a house with 1,860squae feet sold for 95,000 why is that not what the model predicted? My question is to how to solve with excel?
