To construct a 95% confidence interval for the mean, the interval should have a 95% chance of containing μ. Equivalently, in 95% of the confidence intervals so constructed, the resulting interval should contain the true mean μ. For most students in introductory statistics, the above statements represent little more than acts of faith.

Confidence level: The percentage of all CIs (if we took many samples, each time computing the CI) that contain the true parameter. Note: The endpoints of the CI are statistics, calculated from sample data. (The endpoints are random, not the parameter!) In general, if is normally distributed, then in . 100(1 – )% of samples, the interval
