I need to do a project for ap stats. It can be anything im interested in, and i have to perform some tests and all that

I need some ideas!! Somthing that would be interesting..

You could have your class take pretend tests. Maybe 20 questions could be true/false and 20 could have 4 multiple choice answers (a, b, c, d) each. Of course, there are no questions. What are the chances of anyone passing the test?
