     The 'fruitfly' data frame has 9 rows and 3 columns. 125 fruitflies
     were divided randomly into 5 groups of 25 each. The response was
     the longevity of the fruitfly in days. One group was kept
     solitary, while another was kept individually with a virgin female
     each day. Another group was given 8 virgin females per day. As an
     additional control the fourth and fifth groups were kept with one
     or eight pregnant females per day.  Pregnant fruitflies will not
     mate. The thorax length of each male was measured as this was
     known to affect longevity.
