This was very useful! I forgot how to do this outside of excel but I have an upcoming exam that requires all calculations done with a calculator so this is a life saver!

how come it shows ERROR in my TI-84 PLUS? Anybody help?

[fatdumplins]

My TI-84 Plus does not give me the option of not entering mean and standard deviation. Thus my answers are always off. Not sure how to fix that.
