If the absolute value of the test statistic is greater than the critical value 0. These problems are generally of two kinds: 1 those in which the sample size is so large that one may treat a data-based estimate of the as if it were certain, and 2 those that illustrate mathematical reasoning, in which the problem of estimating the standard deviation is temporarily ignored because that is not the point that the author or instructor is then explaining. Notice that the unknown population variance σ 2 does not appear in T, since it was in both the numerator and the denominator, so it canceled.
