Find the standard score (z) such that the area above the mean and below z is about 34% of the area under the normal curve
----
Draw a picture of a normal curve.
-----------------------------------
Center 34% around the mean, keeping 17% to the left and 17% to the right
of the mean.
-----------------------------------
Then the left tail has 0.50-0.17 = 0.33 = 33% of the data.
--
Find the corresponding z-value:
invNorm(0.33) = -0.4399
---
The corresponding value to the right of the mean is +0.4399
