Longevity of fruiflies depending on sexual activity and thorax length

Description

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. One observation in the many group has been lost.
