Majority of the time the population standard deviation will not be known, so this is the less likely of the two tests for a single mean to be used. All tests will be performed by hand and also with the assistance of the TI-84 family and TI-nspire graphing calculators. Both the p-value and rejection region decision rules will be used.

Thirdly, we will explain how to calculate the chi-square critical value for the two-tailed rejection region. Because the χ 2 \chi^2 χ 2 distribution is asymmetrical, we have to calculate two critical values separately.
