a. Use the Wilcoxon rank sum test to conduct a significance test for the bird nest study discussed in Exercise E. 13.
b. Use the Kruskal-Wallis test to conduct a significance test for the bird nest study. Determine whether the distribution of bird size (response is Length) is the same for each nest type. When the chi-square approximation is used, each group should have at least five observations. You may need to create an “other” group to combine all nest types with sample sizes less than five.
