Critical values of the F-distribution (indexed by numerator and denominator degrees’ of freedom) are given in Table B.4, pages 1340-1345. Note that this is a very specific version of the t-test regarding the slope parameter, specifically a 2-sided test of whether the slope is 0.

The calculated chi-square statistic is 252.5 which exceeds the critical value of 15.5 (8 degrees of freedom and (=0.05) by a wide margin calling for a rejection of the null hypothesis that the data conforms to Benford’s Law. The second ranking method was to sort the sales numbers by …

The critical value is approximately 2.00, so we will reject the null hypothesis and conclude that when given a reason for a woman’s anger, she is given more status than when no reason was given for the anger. 14.21 If the two variances are equal, they will be equal to the pooled variance.
