A political scientist was interested in studying America's voting habits. So, he decided to make the least squares regression equation to predict the percentage of people in a state that would vote for Obama in 2012 based on the percentage of people in a state that voted for Obama in 2008. The least squares equation is y-hat = -4.599 +1.04x. In the state of Florida, 50.09% voted for Obama in 2008; whereas, 50.01% voted for him in 2012. What is the value of the residual?
