- How far off are you from the actual number of Beetle larvae from a cottonwood tree with 5 stumps?
-  Does it make sense to use a linear regression model here? Write a short paragraph about your analysis and carefully state your case. You should provide at least 2 specific reasons why this is or is not a good technique to use to predict the number of clusters of beetle larvae.   
- Does it make sense to predict the number of clusters of beetle larvae if there are zero stumps? Why or why not? What happens when you do this calculation?
