Input
Fill in the sample size (\(n\)), the sample mean (\(\bar{x}\)), the sample standard deviation (\(s\)), and the confidence level (CL), then click Calculate. Write the confidence level as a decimal. For example, for a 95% confidence level, enter 0.95.
| Sample Size (\(n\)): | Sample Mean (\(\bar{x}\)): | Standard Deviation (\(s\)): | Confidence Level (enter a decimal): |
Output
| Lower Bound: | Upper Bound: |
