Auditors must make judgments about various aspects of an audit on the basis of their own direct experience, indirect experience, or a combination of the two. In a study, auditors were asked to make judgments about the frequency of errors to be found in an audit. The judgments by th auditors were then compared to the actual results. Suppose the following data were obtained from a similar study; lower scores indicate better judgments. Direct Indirect Combination 17.0 16.6 25.2 18.5 22.2 24.0 15.8 20.5 21.5 18.2 18.3 26.8 20.2 24.2 27.5 16.0 19.8 25.8 13.3 21.2 24.2 Use a = 0.05 to test to see whether the basis for the judgment affects the quality of the judgment.
