Question 404289: I have been studying z-scores but this question has me stumped. I have no idea how to find the z-score a a vertical line. This is the question.
Find the z-score location of a vertical line that separates
a normal distribution as described in each of the
following.
a. 20% in the tail on the left
b. 40% in the tail on the right
c. 75% in the body on the left
d. 99% in the body on the right

To get z-values you need either a calculator like a TI-83 or better,
or a z-chart, which can be found online.
-------
Find the z-score location of a vertical line that separates
a normal distribution as described in each of the
following.
a. 20% in the tail on the left:: invNorm(0.2) = -0.8416
-----------------
b. 40% in the tail on the right:::invNorm(0.6) = 0.2533
-----------------
c. 75% in the body on the left:::invNorm(0.75) = 0.6745
-----
d. 99% in the body on the right:::invNorm(0.01) = -2.2904
