Find the Z-scores that separate the middle 27% of the distribution from the area in the tails of the standard normal distribution.
----
The middle 27% leaves a left tail of (100-27)/2 = 36.5%
-----
Find the z-value with a left tail of 0.365::
Lower z-value = invNorm(0.365) = -0.3451
---
The right tail is symmetric with the left.
Upper z-value = +0.3451
------------
Cheers,
