A real estate agent made a scatter plot with the size of homes, in square feet, on the x-axis and the homeowner's property taxes on the y-axis. The variables have a strong linear correlation, and the equation for the least squares regression line is [tex]\hat{y} = 0.392x + 638.118[/tex].
Based on the equation, what should the agent expect the property tax to be for a 2,400-square foot home in the area?
