I have no idea how to answer this question for my Data Analysis assignment!

The Private School Association conducts a survey of the outcome of private and public school students who pursue university education. The outcome is either graduate eventually or not. It is found that:

60% of commencing freshmen are from public schools.

75% of public student students who commence their university education eventually graduate.

90% of private school freshmen eventually graduate.

Is there any evidence that a freshman’s chance to graduate is dependent on the type of high school they attended?
