  • For the histograms title your charts “Histogram Business Major: Annual % ROI” for Business majors and “Histogram Engineering Major: Annual % ROI” for Engineering Majors. Comment on your results.
  • Question 1 hint/help. Find out how many schools are public and how many are private in each major and do a pie chart (2 charts total). Use the charting function to make a pie chart in Excel. Make sure not to include the total in your pie chart—just the numbers for private and public for each major.Question 2 hint/help. For each major do a frequency distribution (2 charts total)—that is find out how many schools are in each bucket. The buckets will look something like 6%≤x<6.5%, 6.5%≤x<7%, etc. all the way to 10.5%≤x<11%, where x is Annual ROI. Then use these as the text labels for the x axis of your graph—Excel can do this automatically–the y axis will be the number of schools in each Annual ROI bucket.
