WebUsing either method we can find that the critical T-Value is $\approx \underline{-2.045}$ For a two-tailed test we need to check if the test statistic (TS) is smaller than the negative critical value (-CV), or bigger than the positive critical value (CV).. If the test statistic is smaller than the negative critical value, the test statistic is in the rejection region. WebSep 11, 2024 · 16.5: Critical Values for F-Test. The following tables provide values for F(0.05, νnum, νdenom) for one-tailed and for two-tailed F -tests. To use these tables, we first decide whether the situation calls for a one-tailed or a two-tailed analysis and calculate Fexp. where S2 A is greater than s2 B.
