Note:
When computing sample sizes, you must always round up to the next whole
number.
We can also use the
Large Sample Confidence Interval for a Single
Population Proportion
workbook to compute the sample size. The output is
shown
Figure 11- 7
. Observe that the computed sample size from the
workbook is 10,616, the same as when the formula is used.
