Assignment 1) Complete. Great work

Q4) This is the formula for Root mean square PERCENTAGE error, rather than Root mean square PREDICTION ERROR.

Great additional analysis!

Comments on the additional code:

When dropping variables such as cylinders and displacement, should do it one by one and rerun your correlation and model after each variable dropped. This is because it is possible their collinearity might change in absence of other variables.
