In an attempt to model house prices in a certain neighborhood in Oklahoma City, a real estate developer collected data on 58 houses. The data collected are price, area, number of floors, width of street, walking time to public transportation, is at the intersection of two streets or not, amount spent on flooring, alarm system, and central air conditioning.

He/She has thought of building two models:

Model1: Price is a function of area, number of floors, and amount spent on flooring.

Model2: Price is a function of area, number of floors, width of street, walking time to public transportation, is at the intersection of two streets or not, amount spent on flooring, alarm system, and central air conditioning.

1) Write a one-page report in which you present both models and explain which one should be used to estimate house prices in that neighborhood. The report should talk about the significance of the variables in both models also answer question 2) (below).

2) There is a problem with air conditioning and flooring because the cost of each one of them increases with an increase in the area of the house. How can you solve this problem?
