Truffles are a great delicacy, sending thousandsof mushroom hunters into the forest each fallto find them. A set of plots of equal size in anold-growth forest in Northern California wassurveyed to count the number of truffles (Wateret al. 1997). The resulting distribution is pre-sented in the following table. Are truffles ran-domly located around the forest? If not, are theyclumped or dispersed? How can you tell?

Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this cholce of d.f. may Increase the Pvalue by a small amount and therefore produce a slightly more "conservative" answer.
