a. Is there significant evidence of a difference among the three topography classifications of the forests relative to their biodiversity as measured by Fisher€™s alpha. Use annual precipitation to adjust for differences in the five regions.
b. Provide a grouping of the three topography classifications based on their adjusted mean Fisher€™s alpha.
c. Using residual plots, evaluate whether the conditions needed to properly answer parts (a) and (b) are valid for this data set.
