CONFIDENCE INTERVAL for proportions Calculator

Fill in the sample size (n), the number of successes (\(x\)), and the confidence level (CL). Write the confidence level as a decimal. For example, for a 95% confidence level, enter 0.95 for CL. Then hit Calculate and assuming \(np\) and \(nq\) are large enough, the correct confidence interval will be calculated for you.

n: | \(x\): | CL: | Lower Bound | Upper Bound | \(\hat{p}\) |
