sampling.
33) Consider the steps in sampling for tests of details and for tests of controls. Explain the
differences in applying sampling to these two types of tests.

sections: plan the sample, select the sample and perform the audit procedures, and evaluate the
results. Discuss 5 of the 9 steps included in the "plan the sample" section for nonstatistical
sampling.
36) When using nonstatistical sampling, the auditor must subjectively consider whether the true
population misstatement exceeds a tolerable amount. This is done by considering five factors.
One factor is the difference between the point estimate and tolerable misstatement. State the
other four factors the auditor must consider.
37) Discuss each of the six possible courses of action the auditor can take when he or she has

risk model is needed.
39) The larger the sample size, the more confident the auditor can be that the point estimate is
close to the true population value.
40) Acceptable risk of incorrect acceptance is directly affected by acceptable audit risk.
41) Tolerable misstatement is inversely related to sample size.
42) Acceptable risk of incorrect acceptance (ARIA) and sample size are inversely related; that is,
as ARIA increases, sample size decreases.
43) Estimated misstatement in the population and sample size are inversely related; that is, as
estimated misstatement increases, sample size decreases.
44) The purpose of stratification is to permit auditors to emphasize certain aspects of a
population and deemphasize others.
45) An auditor using nonstatistical sampling cannot formally measure sampling error.
46) If the misstatement in a population is larger then tolerable misstatement without considering
sampling error, the population will be considered unacceptable.
47) If a population is not considered acceptable, and the analysis indicates an individual error is
unique or most of the misstatements are of a specific type, it may be appropriate to restrict the
additional audit effort to the problem area.
48) Required sample size increases as the auditor's tolerable misstatement for an account balance
or class of transactions decreases.
49) The primary factor affecting the auditor's decision about acceptable risk of incorrect
acceptance (ARIA) is assessed inherent risk.
50) In stratified sampling, a maximum of four stratum can be used.
51) ARIA measures the auditor's desired assurance for an account balance.
52) Acceptable audit risk and acceptable risk of incorrect acceptance are inversely related; that
is, as AAR increases, ARIA decreases.
