The Normal Probability Distribution

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?
