Question 859889: If X is a normal random variable with a mean of 6 and standard deviation 2.5, then find the value x such that P(Z>x) is equal to .7054. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! If X is a normal random variable with a mean of 6 and standard deviation 2.5, then find the value x such that P(Z>x) is equal to .7054.
------
Find the x-value with a right tail of 0.7054
========
invNorm(1-0.7054) = invNo-0rm(0.2946) = -0.5400
--------
x = z*s+u
x = -0.5400*2.5+6 = 4.65
