A Z-test is any statistical test for which the distribution of the test statistic under the null hypothesis can be approximated by a normal distribution. Z-tests test the mean of a distribution. For each significance level in the confidence interval, the Z-test has a single critical value (for example, 1.96 for 5% two tailed) which … See more Because of the central limit theorem, many test statistics are approximately normally distributed for large samples. Therefore, many statistical tests can be conveniently performed as approximate Z-tests if the sample size is large … See more How to perform a Z test when T is a statistic that is approximately normally distributed under the null hypothesis is as follows: First, estimate the See more For the Z-test to be applicable, certain conditions must be met. • Nuisance parameters should be known, or estimated with high accuracy (an example of a nuisance … See more Location tests are the most familiar Z-tests.
