# Agronomists are interested in determining conditions that increase the yield of crops.  In one
#   experiment 80 1-acre plots of corn are randomly divided into two groups of 40 plots each.  An
#   insecticide is used on each plot in one group and sterilized male individuals of an insect pest
#   are released on the each plot of the other group.
# group: Tratment for the plot
# yield: yield (bushels) for the plot
