11) Which of the following statements best expresses the impact that the performance of audit procedures has on statistical vs. nonstatistical sampling? A) Audit procedures on the sample item will vary as a result of using either statistical or nonstatistical sampling. B) The audit procedures will be the same for either statistical or nonstatistical sampling but they must be performed differently for each. C) Statistical sampling requires quantitative audit procedures, whereas nonstatistical sampling requires judgmental audit procedures. D) Audit procedures on the sample item will not vary as a result of using either statistical or nonstatistical sampling.
