To evaluate if auditors might be helped in determining the chances of fraud if they carefully measure cash flow, samples of midlevel auditors from CPA firms were asked to indicate the chance of material fraud on a scale from 0 to 100 for a case. A random sample of 39 auditors used the cash-flow information. Their mean assessment was 33.31, and the sample standard deviation was 22.41. For an independent random sample of 39 auditors not using the cash-flow information, the sample mean and standard deviation were respectively 47.53 and 27.3. Test at the 10% level the assumption that the population variances were the same for auditors using cash-flow information as for auditors not using cash-flow information against a two-sided hypothesis. Assume the populations are normally distributed. To test the assumption that the population variances for assessments of the chance of material fraud were the same for auditors using cash-flow information as for auditors not using cash-flow information against a two-sided hypothesis, identify the null and alternative hypotheses. Choose the correct answer below. A. Ho: 0 0 H: 0 <0 . Ho: 0 so H: 0 >0 C. Ho: 02 D. Ho: 0 = 0 H: H:00 The test statistic is F = . (Round to three decimal places as needed.)
