WebApr 11, 2013 · So, when you compare the computed test statistics and critical value, you have to reject the null if computed value is smaller than critical value (note that this is one (left) tailed test). In your case,-1.987 is not smaller than -3.580 (1% critical value) [Try not to use the absolute value because that is usually applied to two-tailed test ... WebYou compare the (observed) F-value to the critical F-value. The critical F-value is a value for which Pr(F > F crit H0) = alpha, with alpha being the level of significance (the "size" of the test). bd sdカードコピー
