How many are you going in knowing? I am thinking: 5% one tail or 10% two tail= 1.65 2.5% one tail or 5% two tail = 1.95 Any others?
Thats 1% one tail?
right, 99% - 2.33
3 Standard deviation I meant
what? I thought they will give us that in the question. Why would CFAI want us to memorize something totally useless? well, then again… The only one I am memorizing is 1.65 for 5% and 1.95 for 2.5%.
