Example 10-3
In addition, we can also use the
Sampling Distribution of the Sample
Mean
workbook to get the answer. This is shown in
Figure 10-18
. Recall
in the original problem we did not know the sampling distribution. Hence
we will not assume normality for the sampling distribution. The output in
Figure 10-18
assumes that the sampling distribution is not normal.
