If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate. More precisely, it's actually 1.96 standard errors. This is called a critical value (z*). We can calculate a critical value z* for any given confidence level using normal distribution calculations. russell crowe sharon stonerussell crowe spit on azalea banksWeb1 Answer. If you know the exact distribution of the test statistic, and use that distribution's quantiles to make confidence intervals, that interval is exact.
