Here are tables of the Standard Normal and Student’s t distributions. The formulas for the first value in each P column are, respectively =NORMSDIST(A3) and =TDIST(C3,20,2), where column A is the one labeled “Z” and column C is labeled “t”.
I need some help in finding the meaning of the number given in the P column under NORMSDIST? and the meaning of the number given in the P column under TDIST?
and if it is a probability. What probability is it?
This solution explains the use of some of the probability functions in Excel.
