As part of this analysis, Motor Trend is particularly interested in the following two questions:

• Is an automatic or manual transmission better for MPG
• Quantify the MPG difference between automatic and manual transmissions

3. Did the student fit multiple models and detail their strategy for model selection?
4. Did the student answer the questions of interest or detail why the question(s) is (are) not answerable?
