<PRE><B>Question 1118356</B>
The average salary of merchandisers is $57,000 per year with a standard deviation of $7000. 
e.	What is the average salary below which 17% of the merchandisers earn? (Round the final answer to the nearest whole number.)
Find the z-value with a left tail of 0.17
invNorm(0.17) = -0.9542
Find the corresponding salary value.
x = z*s+u = -0.9542*7000+57000 = $50320.84
--------------------------

f.	What is the average salary above which the top 10% of the merchandisers earn? (Round the final answer to the nearest whole number.)
Find the z-value with a right tail of 0.10
invNorm(0.90) = 1.2816
Ans: x = 1.2816*7000+57000 = $65970.86
