16.16 Counts of seeds in one-pound scoops.

Exercise 7.55 (page 395) discusses a study of two different packaging plants in terms of the packaging of seeds. An SRS of 50 one-pound scoops of seeds was collected from Plant 1746, and an SRS of 19 one-pound scoops of seeds was collected from Plant 1748. The number of seeds found in each scoop was recorded. Histograms and Normal quantile plots suggest the data arise from non-Normal distributions. Using software, is there a significant difference in the number of seeds per pound between the two plants based on the Wilcoxon test?
