d) (20 points) Calculating and/or stating any other quantities you believe are important, make and justify a recommendation for the Office of Student Life regarding which aspects they should put the most focus on in their programming to improve student success at NAU.

Show your work and justify your recommendation in a paragraph or more or discussion.
