Example 9-7
:
Find the area under the standard normal distribution curve
between
= -2.32 and
= 1.91.
Solution:
This is equivalent to finding
P
(-2.32
1.91). That is, we
need to find
P
(-2.32
1.91). Using the
Normal Probability
Distribution
workbook to solve, we get the value of 0.9618. Thus,
P
(-2.32
1.91) = 0.9618. The result is shown in
Figure 9-29
