Steve Caplets, a real estate appraiser in Lake Charles, Louisiana, has developed a regression model to help appraise residential housing in the Lake Charles area. The model was developed using recently sold homes in a particular neighborhood. The price (Y) of the house is based on the square footage (X) of the house. The model is:
Â
The coefficient of correlation for the model is 0.63.
Â

Â
(a) Use the model to predict the selling price of a house that is 1,860 square feet.
Â
(b) A house with 1,860 square feet recently sold for $95,000. Explain why this is not what the model predicted.
Â
(c) If you were going to use multiple regressions to develop an appraisal model, what other quantitative variables might be included in the model?
Â
(d) What is the coefficient of determination for this model?
