The class intervals include the left hand endpoint, but not the
right hand endpoint.  For instance, the third line of the table
states that 20% of the estimates of jelly bean consumption ranged
from 300 to 499.
     Suppose you want to make a percentage histogram of the data
reported in this table.  Then the height of the rectangle over
the class interval 3 - 5 would be closest to
