To demonstrate how your model works, make a prediction where you select the independent as the mean of each independent variable in the data.
2. Using the same data, compute a quadratic regression model. Similarly as above, thoroughly explain the results, and only include the relevant variables. Compute a prediction using the same input as in 1.
3. Which model should be used, the one from 1. or the one from 2? Why?
