The following is a list of the variables in the database: <br \/>FloorArea: square feet of floor space <br \/>Offices: number of offices in the building <br \/>Entrances: number of customer entrances <br \/>Age: age of the building (years) <br \/>AssessedValue: tax assessment value (thousands of dollars) <br \/>Use the data to construct a model that predicts the tax assessment value assigned to medical office buildings with specific characteristics. <br \/>Construct a scatter plot in Excel with FloorArea as the independent variable and AssessmentValue as the dependent variable. Insert the bivariate linear regression equation and r^2 in your graph.

What is the overall fit r^2? What is the adjusted r^2? <br \/>Which predictors are considered significant if we work with \u03b1=0.05? Which predictors can be eliminated? <br \/>What is the final model if we only use FloorArea and Offices as predictors? <br \/>Suppose our final model is: <br \/>AssessedValue = 115.9 0.26 x FloorArea 78.34 x Offices <br \/>What wouldbe the assessed value of a medical office building with a floor area of 3500 sq. ft., 2 offices, that was built 15 years ago?
