Quick Reference

A test, using a sample of n independent observations, of the null hypothesis that a normal distribution with variance σ2, has mean μ. Writing the sample mean as , the test statistic is z, given by In the case where the alternative hypothesis is that the mean is not μ, then, if |z| > 1.96, there is evidence to reject the null hypothesis at the 5% significance level in favour of the alternative hypothesis. See hypothesis test.
