Question 798212: 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. (Round z value to 2 decimal places. Round your answer to 2 decimal places.) Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 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
