The frequencies were found to be 68, 40, 18, 19, 8, 20, 6, 9, 12 and those digits correspond to the leadin" rel="nofollow">ing digits of 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. If the observed frequencies are substantially different from the frequencies expected with Benford's law, the check amounts appear to be the result of fraud. Use a 0.05 significance leveÕÉ≠†Њ†l to test for goodness­of­fit with Benford's law. 1. Calculate the χ2 test statistic.
