Description
The Normal Probability Distribution
Discussion 3 Instructor’s Notes;
The discussion is an exercise in using the probability tables—and then talking about it. Post early—there is not really much to say. If you have a loose-leaf book, the table is obviously not on the inside front cover—all the tables are in Appendix B: Tables.
In §6.2 we are introduced to the Normal Probability Distribution and the special case of the Normal Probability Distribution, the Standard Normal Probability Distribution, which is a Normal Probability Distribution with mean (u) zero and variance (σ2) one.
One way to find probabilities from a Standard Normal Distribution is to use probability tables, which are located inside the front cover of your textbook.
- According to the table, what is the probability when z ≤ -1.75? The probability when z ≤ 1.75?
- What properties of probability distributions and specifically the Normal Probability Distribution do you notice from the two probabilities that you have found in the table?
