I need to know how to find the probability that z0 is greater than or equal to 2.40 using my TI-83+. The answer is .008200, but I don't know how to get that using my calculator. The only reason I know the answer is because it is an example from my homework. Please help! On a side note, this is for a test so I need to know how to do it on my calculator, I know there is a chart in the back of my book that I can use, but I can't use my book on my test. Thanks.
