Use a Z-Table. Step 1: Find the alpha level. If you are given the alpha level in the question (for example, an alpha level of 10%), skip to step 2. Subtract your confidence level from 100%. For example, if you have a 95 percent confidence level, then 100% – 95% = 5%.
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.
