Assuming that the relation is linear, does it mean that there are more speeding tickets on well paved roads? A random sample of records of electricity usage of homes gives the amount of electricity used in July and size (in square feet) of 135 homes. A regression was done to predict the amount of electricity used (in kilowatt hours) from size. The residuals plot indicated that a linear model is appropriate. What units does the slope have?
