Assume that Z has a standard normal distribution. Use Appendix Table III to determine the value for z that solves each of the following:
(a) P(Z <z) = 0.9 (b) P(Z <z) = 0.5
(c) P(Z >z) = 0.1 (d) P(Z >z) = 0.9
(e) P(−1.24< Z < z) = 0.8
ANSWER:
Solution:
Step 1 of 6:
It is given that the random variable Z has the standard Normal distribution.
We are given with some probability values.We need to find the value of z which yields this given probabilities using the cumulative Standard Normal Distribution table.
