WebA critical value is a cut-off value (or two cut-off values in the case of a two-tailed test) that constitutes the boundary of the rejection region (s). In other words, critical values divide the scale of your test statistic into the rejection region and the non-rejection region.

WebThe confidence intervals for the difference in means provide a range of likely values for (μ 1-μ 2). It is important to note that all values in the confidence interval are equally likely estimates of the true value of (μ 1-μ 2).
