The formula for estimation is:
where:
= sample mean
= t statistic determined by confidence level
= standard error =
given
A % Confidence Interval will have the same critical values (rejection regions) as a two-tailed test with .
so, z-score for % confidence interval is ±
% confidence interval is [, ]
You can be % confident that the population mean () falls between and .
