Question 234470: For a standard normal distribution, find:
P(z > c) = 0.2464
and P(z < c) = 0.9798
Find c.

You can put this solution on YOUR website! to work these, draw a normal curve and try
to get a picture of the area or interval
described in the problem.
-------------------------------------
For a standard normal distribution, find:
P(z > c) = 0.2464
That is some z-value that gives you 0.2464 as a right tail.
1-0.2464 = 0.7536
That is the corresponding left tail.
c = invNorm(0.7536) = 0.6859
----------------------------------------
and P(z < c) = 0.9798
That is a large left tail.
invNorm(0.9798) = 2.0496
=========================================
