The file 110data.dat contains answers to the first part of the "Class 
Data" questionnaire passed out in Stats 110A and 110B during the first week 
of Spring 99.  The first column indicates which class the questionnaire 
comes from.  Columns 2-9 are:
	2) height (inches)
	3) weight (pounds)
	4) sex (m/f)
	5) age (years)
	6) days since last alcoholic drink (NEVER is coded as 10000)
	7) Hours of TV watched last night
	8) Expected Grade
Missing values were coded with a "?".  ARC has no problem with this, but 
other packages might have their own preferences. (For example, JMP prefers 
a ".", and Splus a numerical value or "NA".
