Extracted text: The table below 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. When using these data to test for goodness-of-fit with the distribution described by Benford's law, identify the null and altenative hypotheses.

Extracted text: The table below lists days of the week selected by a random sample of 1023 subjects who were asked to identify the day of the week that is best for quality family time. Consider the claim that the days of the week are selected with a uniform distribution so that all days have the same chance of being selected. If we test the claim using the goodness-of-fit test, what is actually tested? Sun Mon Tues Wed Thurs Fri Sat 525 25 10 20 12 42 389 Choose the correct answer below O A. The test is to determine whether the observed frequency counts agree with the claimed uniform distribution so that the frequencies for at least two days are equally likely. O B. The test is to determine whether the observed frequency counts agree with the claimed uniform distribution so that the frequencies for the different days are equally likely. OC. The test is to determine whether the observed frequency counts agree with the claimed uniform distribution so that the frequencies for only two days are equally likely. O D. The test is to determine whether the observed frequency counts agree with the claimed chi-sauare distribution so that the frequencies for at most three days are equally likely.
