a. Estimate the sample regression equation that enables us to predict property taxes on the basis of the size of the home. (Round your answers to 2 decimal places.)
taxes = ______ + ______ size
b. Interpret the slope coefficient.
a. As Property Taxes increase by 1 dollar, the size of the house increases by 6.78 ft.
b. As Size increases by 1 square foot, the property taxes are predicted to increase by $6.78.
c. Predict the property taxes for a 1,500-square-foot home. (Round coefficient estimates to at least 4 decimal places and final answer to 2 decimal places.)
