The Australian Government’s Energy Efficiency Opportunities
program encourages large energy using businesses to improve their
energy efficiency. It does this by requiring businesses to
identify, evaluate and report publicly on cost effective energy
savings opportunities. As part of the process of identifying
factors impacting on electricity consumption, a large super market
chain took a sample of 30 stores and investigated the relationship
between electricity consumption and store size. Consider the simple
regression model: consi = β0 + β1sizei +εi
