The crab spider, Thomisus spectabilis, sits on flowers and preys upon visiting honeybees. Do honeybees distinguish between flowers that have crab spiders and flowers that do not? To test this, Heiling et al. (2003) gave 33 bees a choice between two flowers, one of which had a crab spider and the other of which did not. In 24 of the 33 trials, the bees picked the flower that had the spider. In the remaining nine trials, the bees chose the spiderless flower. With these data, carry out the appropriate hypothesis test, using an appropriate approximation. (This problem is from Ch. 10 "The Normal Distribution" if that affects the procedure at all.)
