How much does it cost to commute to work? How does distance of your commute relate to your fuel usage? Data were collected on distance between a person\'s home and primary work location (distance) and the person\'s monthly expenditures on gasoline for their vehicle (gas) for 17 individuals. The regression analysis is given below.

One of the 17 individuals in the sample lived 12 miles from work and spent $139.25 on gas. What is this individual\'s residual value?

Give your answer to 2 decimal places. For help on how to input a numeric answer, please see \"Instructions for inputting a numeric response.\"

Solution

hey, to find residual.....you have to post the regression analysis!

Now, I am explaining in a general manner!
Let,  y = a x + b is the regression equation.....

The actual value of dependent variable is y_i......

The predicted value of y_i is = y^{^}_i

y^{^}_{i =} a x_i + b
The residual is the error that is not explained by the regression equation...
i.e, residual= e_i = y_i - y^{^}_i
