Good afternoon,
I am interested in the factors that affect the selling price of a house in the following problem question: Please help!
data from 27 houses is collected . For each house we record the"Selling price"and, except from the"Size"of the house, we also record the age of the house, the number of bedrooms and the number of bathrooms. The variable"Selling price"was recorded in SPSS in"thousands of euros"(i.e. 1 unit=?1000),the variable"Size of house"was recorded in square meters (i.e. 1 unit=1 square meter, m2), while the age of the house is in years.
SPSS the decimal point is denoted by the dot (.), (e.g. 21.892 is around 21).
I am given the following output from SPSS (attached)
Can you please assist in the following questions with explanations step by step?
(1) . What we conclude If we perfom an F test? Can you show the steps to understand?
(2)Based on the conclusion from part (1) we need to continue to test individually which of the variables are significant for the model? How we do that? Can you show the step to understand it?
(3)What is the final estimated model and how to interpret the coefficients?
(4)Is the final model better than the model which included only the Size of the House as an independent variable? how we explain it??
(5)What will be the selling price of a house that has size 300 square meters, it has 3 bedrooms, it is 10 years old and it has 2 bathrooms.
