P. p. pumpkineater, the renowned agricultural geneticist, has mutated previous varieties of pumpkins and produced two new strains, scaryface and candlebreath. because he has limited marketing funds, he must decide which strain is the most "jack-o-lanternable." having been in the jack-o-lantern business for a long period of time, he has developed the pppjol test to compare different strains. the plot of land available for planting is on the side of a hill with a large number of trees on top and a stream near the bottom. he is quite concerned about the effects of sunlight and water on the growth of the pumpkins. he has 60 seeds of each variety available for testing. design an experiment that will p. p. determine which strain to market.
