Question 540986
Given a normal distribution of values for which the mean is 140 and the
standard deviation is 33, find the 90th percentile for this distribution.
Round your answers to 3 decimal places.
-----
Find the z-value with a left tail of 90%
invNorm(0.90) = 1.2816
---
90th %ile score = z*s + u = 1.2816*33 + 140 = 182.291
