Chapter 9: The Normal Probability Distribution

Area for
P

Example 9-6:
Find the area under the standard normal distribution curve
between
= -1.99 and
= -0.66.
Solution:
This is equivalent to finding
P
(-1.99
-0.66). That is, we
need to find
P
(-1.99
-0.66). Using the
Normal Probability
Distribution
workbook to solve, we get the value of 0.2313. Thus,
P
(-1.99
-0.66) = 0.2313. The result is shown in
Figure 9-27.
