An analyst believes that the price of an IBM stock is a normally distributed random variable with mean $105 and variance 24. The analyst would like to determine a value such that there is a .90 probability that the price of the stock will be greater than the value. Find the required value.
----------------------
Find the z-value with a 0.90 right tail: invNorm(0.10) = -1.2816
---
Use x = zs+u to find the corresponding price.
-----
price = -1.2816*24+105 = $74.24
