Question
1. (15 points total) An article by Warton and Hui (2011, Ecology) discusses the
proportion of fish with empty stomachs found in randomly sampled fish collected
from different trophic categories (i.e. detritivores=bottom feeders,
invertivores=invertebrate eaters, omnivores=anything eaters, and piscivores=fish
eaters). Use the data below to answer the following questions.

a. Provide an appropriately labeled boxplot showing the distribution of the
proportions of empty stomachs by each trophic group.
b. A specific type of data transformation is needed before we can conduct this
analysis. State the type of transformation needed and apply it to the response
values to create a new column of data for subsequent analysis. Show the steps
in creating this new column of data (e.g. fish$trans=f(fish$percent)).

c.Conduct a statistical analysis of this transformed data to test the hypothesis that the
proportion of fish with empty stomachs is the same for each trophic group. Provide the
summary in a nicely formatted table and discuss your overall conclusions.
