Estimate the Population Proportion from Summary Data

It is common to have only the "tally" of responses to a question and to want to use this sample result to estimate the proportion for the population. You can do that with the estimate proportion object.

1. Create an estimate by dragging one from the shelf or by choosing Object | New | Interval Estimate.

2. From the pop-up menu in the estimate's upper-right corner, choose Estimate Proportion.

3. Type in the numbers and names of the category and attribute.
