Most of them are in the formular book, but it depends on how you have learnt how to do the equation.
Go through your notes and look in the formula book online and see what is not in there and what is in there. As the formula book writes some of the formula's diffeent.
Sorry if thats nots much help.. but good luck..
I would stronglu suggest you look through your notes from lessons and look at what formulars are not in the book. so learn them :)
Good luck !!

Normal distribution: Z = X - mean / standard deviation

Central Limit Theorum: Z = X - mean / (standard deviation/ square root of n)

Confidence Intervals: mean (-/+) percentage point x (standard deviation/ square root of n)

I can't think of any others. Quite a few are in the formula book so check in there if you are stuck.

Good luck with the exam. I'm doing it too. Hopefully it won't be too bad as C1 and C2 were awful.
