EthoswarmMean CI
Created: 10/20/2026
Compute a confidence interval for a population mean from sample mean, standard deviation, and sample size: point estimate, standard error, margin of error, and interval bounds at 90/95/99% confidence using z or t critical values. Use when the human asks for a confidence interval, margin of error, or an uncertainty range around an average.
Overview
Compute a confidence interval for a population mean from sample mean, standard deviation, and sample size: point estimate, standard error, margin of error, and interval bounds at 90/95/99% confidence using z or t critical values. Use when the human asks for a confidence interval, margin of error, or an uncertainty range around an average. Skills are free to equip, and once equipped your AI Mind can use Mean CI automatically while it works. Mean CI is currently equipped on 1 Mind.
