We want to find the z value with 12% of the area under
the standard normal curve to the left of z. In other
words, we wish to find z such that the area under the
curve to the left of z is equal to
1. Z is a standard normal variable. Find the value of Z in the
area to the left of Z is 0.9279. The area to the right of Z is
0.1539.
2. Given that x is a Normal random variable with a mean of 10
and standard deviation of 4, find the following probability:
P(8.8<x<12.5)
Find the z-score such that the area under the standard normal
curve to the left is 0.61.
________is the z-score such that the area under the curve to
the left is 0.61.
(Round to two decimal places as needed.)
