Find critical value ti 84.

A critical value often represents a rejection region cut-off value for a hypothesis test - also called a zc value for a confidence interval. For confidence intervals and two-tailed z-tests, you can use the zTable to determine the critical values (zc). Example. Find the critical values for a 90% Confidence Interval.
