This is then used to estimate the population standard deviation towards generating the required standard error (Mendenhall, Beaver and Beaver, 2009). In testing for mean, and using the test statistic approach to a two-sided hypothesis for a known standard deviation, a researcher would formulate a two-sided null hypothesis. For an unknown population standard deviation, a →
