BOB - STATISTICS

ok so this is my BOB for the statistics unit so here i go...
as well all know this unit is a toughy and yes i'll admit it's not my favorite =\ but since i need a good mark on this test i wanna make sure i get through it in 1 piece. Maybe after i read over everything a few times it'll stick but as of right now i feel we've learned so much that it's in my head just floating around all unorganized. one of my most biggest weaknesses is identifying when to use normalc/pdf or binomialc/pdf.. i understand when to use either cdf or pdf but it's the normal or binomial that confuses me now.

ok i'm going to go on studying since................ MR. K. I GOT MY BINDER BACK! =)
