Answer:
The value of residual is 2.5131%.
Step-by-step explanation:
We are given the following in the question:
The above is a linear 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.
Independent Variable:
Percentage of people in a state that voted for Obama in 2008
Dependent Variable:
Percentage of people in a state that would vote for Obama in 2012
In the state of Florida, 50.09% voted for Obama in 2008; whereas, 50.01% voted for him in 2012.
Thus, the actual value is 50.01%.
We predict the value from regression equation by putting x = 50.09
The predicted value for percentage of people in a state that would vote for Obama in 2012 is 47.4969%.
Residual is the difference between the predicted value and the actual value.
Thus, the value of residual is 2.5131%.
