The DF is equal to the number of observations minus the number of parameters estimated. Next, calculate the alpha level for your test. The alpha level is usually 0.05 or 0.01. Finally, consult a table of critical values for the appropriate distribution.

WebZ-tables can help you find the critical z-values for a z-test. To find these values, you need to know the significance level and whether you’re performing a one- or two-tailed test. In a hypothesis test, the results are statistically significant when the test statistic exceeds a critical value. Z-tests use z-values for its test statistic.
