An investigator analyzed the leading digits from 789789 checks issued by seven suspect companies. the frequencies were found to be 244244, 148148, 7979, 6161, 4949, 5555, 4343, 4545, and 6565, and those digits correspond to the leading 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 shown below, the check amounts appear to result from fraud. use a 0.0250.025 significance level to test for goodness-of-fit with benford's law. does it appear that the checks are the result of fraud?
