By reviewing the graduation rate for students taking MSC courses, UIW believes that at least 85 percent have completed an undergraduate degree as originally planned. To make sure their percentage is accurate, I have developed a spreadsheet and learned that out of 120 students who took my class in the course of 1 year, 114 have completed the undergraduate degree as originally planned. Would you agree with UIW that at least 85 percent have completed an undergraduate degree as originally planned? (Hint Hint: you are working a proportion). What is the z-score?
