I am interested in finding a non-graphing calculator that helps find the z value give the area under the curve. For example, I want to find a value of a such that $P(Z \leq a) = 0.75$. I am having a casio fx 115es plus. I have done some research online and it seems to me that TI calculator has a built-in function call "Invnorm", but it is a waste of money to buy such a product just for the invnorm function. Thank you in advance!
