Question
The accompanying data table lists leading digits of 317 inter-arrival Internet traffic times for a computer, along with the frequencies of leading digits expected with Benford's law. The accompanying technology results are obtained when testing for goodness-of-fit with the distribution described by Benford's law, and Ho is rejected. What does this result suggest about the possibility that the computer has been hacked? Is there any corrective action that should be taken? Click here to view the data table.
