/* (1) Does repair record (using all 5 categories) predict
      vehicle gas mileage?
	  - What category has the lowest predicted mpg?
	  - What category has the highest predicted mpg?
	  - Come up with a hypothesis test that compares these two categories.
	    (This might require a little thought.)
*/
/* (2) Does repair record predict vehicle price?
	  - What category has the lowest predicted price?
	  - What category has the highest predicted predicted?
	  - Come up with a hypothesis test that compares these.

/* (3) Does race (as defined in the ACS) predict yearly personal income?
	  - What category has the lowest predicted price?
	  - What category has the highest predicted predicted?
	  - Come up with a hypothesis test that compares these.
	    (There is a puzzling result here!)
