Data collected on the workforce at your company yielded a mean height of 67.25 inches and a standard deviation of 2.5 inches. Calculate the 5th percentile, the 75th percentile, and the 90th percentile for your workforce.

5th %ile::
Find invNorm(0.05) = -1.6449
5th %ile = -1.6449*2.5+67.25
---------------
75th %ile
Find invNorm(0.75) = 0.6745
75th %ile = 0.6745*2.5+67.25
------
You should be able to figure out the 90th %ile: it's 70.45
