Diana Sessor, the tax assessor for Brookfield, believes that the value of residential housing is related to how close the housing is to a school. To test this, she randomly selects 100 houses in Brookfield. Her dependent variable is the house’s assessed value in dollars per square foot. Her independent variable is distance in yards to the nearest school. A regression analysis produces the following result:
 = 63.45 – .047X r2 = .35 Sy|x = 9.5 sb = .012
Interpret the slope, intercept, and coefficient of determination. What is Sessor’s hypothesis? Evaluate this hypothesis. What is your best guess as to the assessed valuation per square foot of a house located 200 yards from a school?
