Question 939535: Find the standard score (z) such that the area above the mean and below z is about 34% of the area under the normal curve
Using the z (a) notation (Identify the value of a used within the parenthesis)
Area=0.92 to the left of z

Find the standard score (z) such that the area above the mean and below z is about 34% of the area under the normal curve
---------------
Draw the picture so you can see what you are doing.
Note:: The area to the right is 0.5000-0.3400 = 0.1600
----
Use a z-table or calculator to find the z-value with a right tail of 0.16
I use a TI-84:: z = invNorm(0.84) = 0.9946
-------------------
Using the z (a) notation (Identify the value of a used within the parenthesis)
Area=0.92 to the left of z
Ans: a = invNorm(0.92) = 1.4051
