10.1.2

Table #10.1.6 contains the value of the house and the amount of rental income in a year that the
house brings in ("Capital and rental," 2013). Create a scatter plot and find a regression equation
between house value and rental income. Then use the regression equation to find the rental
income a house worth $230,000 and for a house worth $400,000. Which rental income that you
calculated do you think is closer to the true rental income? Why?
