Find the value of z such that approximately 13.31% of the distribution lies between it and the mean.
----
Draw a normal curve and put the mean in the middle.
---
Shade an area of 13.31% to the left of the mean.
That has a left tale of 50-13.31 = 36.69%
-----
Find the z-value with a left tail of 36.69%:
---
z = invNorm(0.3669) = -0.3401
===============================
Similarly, if you shade the area on the
right side of the mean you will get a
z-value of +0.3401
==========================
