Household energy expenditure. Refer to the annual total household expenditure on energy from 2011 to 2020, Exercise 11.29 (p. 661). From among the variables in the file, you selected one as the dependent variable, y, and another as the independent variable, x, and ran a simple linear regression. Now select a different independent variable and run another simple linear regression. Which of the two independent variables is a more accurate predictor of your chosen dependent variable? Explain.
