<PRE><B>Question 798212</B>
A normal distribution has a mean of 50 and a standard deviation of 4.

Determine the value below which 95 percent of the observations will occur.
----
Find the z-value with a left-tail of 0.95.
invNorm(0.95) = 1.65
-----
To find the corresponding x-value use x = z*s+u
x = 1.65*4+50 = 56.58
