Practical interpretation of the parameter estimates
Example predictions, including prediction intervals for several different vehicle profiles (e.g. type of car, make, model, etc. as appropriate to your solution)
Justification that your final model meets the regression assumptions
The project will be graded based on:

The quality of the final model
The model justification/validation
Practical interpretation
Example predictions
Formatting of the report

You need to use sas to analyze the data
