# Statistics - Normsdist and Tdist

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".

What is the meaning of the number given in the P column under NORMSDIST?

The values in the P column under NORMSDIST give the areas under the Standard Normal Curve

( = 0, = 1) from z = - to z = the table z- ...

#### Solution Summary

The meaning of the number given in the P column under NORMSDIST and under TDIST are computed.
