Relevant Information: %	This data set was generated to model psychological%	experimental results.  Each example is classified as having the%	balance scale tip to the right, tip to the left, or be%	balanced.  The attributes are the left weight, the left%	distance, the right weight, and the right distance.  The%	correct way to find the class is the greater of %	(left-distance * left-weight) and (right-distance *%	right-weight).  If they are equal, it is balanced.%%5.
