Exact Confidence Intervals for a Single Proportion
This Demonstration shows calculations of point estimations and confidence intervals for various single proportions of populations obeying a condition (or trait), as well as their plots versus -value. This is done for differing populations obeying and violating a condition (or trait) and differing -values for estimating the lower and upper bounds of the confidence intervals.
