9.42 What nonparametric test can be used to compare the distribution of pod weight for inoculated vs. noninoculated plants?
9.43 Use the computer to perform a permutation test approach to implement the test mentioned in Problem 9.42 and report a two-tailed p-value.
9.44 Compare your results with those obtained in Problem 8.113 (p. 330).
