Complete the following steps to specify the data for the sample size calculation.

- Select Calculate sample sizes.
- In Minimum percentage of population in interval, enter the minimum percentage of the population that you want a two-sided tolerance interval to include, or a one-sided interval to be greater than (lower bound) or less than (upper bound).
- In Maximum acceptable percentages of population in interval (p*), enter the maximum percentage of the population that you want a two-sided tolerance interval to include, or a one-sided interval to be greater than (lower bound) or less than (upper bound).
###### Tip

If you enter multiple values into a field, separate the values with a space. You can also use shorthand notation to indicate multiple values. For example, you can enter 10:40/5 to indicate sample sizes from 10 to 40 in increments of 5.

- In Sample sizes, enter the number of observations for each sample. To assess the effect of different sample sizes, enter multiple values. Larger sample sizes make the tolerance interval more precise.
