10) Which of the following statements is most correct?
A) A sample of all items of a population will eliminate sampling risk, but increase
nonsampling risk.
B)The use of an appropriate sample selection technique ensures a representative sample.
C) The auditor's failure to recognize an exception is a significant cause of sampling risk.
D) The use of inappropriate audit procedures is a significant cause of nonsampling risk.
Answer: D
Terms: Sample selection; Sampling and nonsampling risk

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.
Answer: D
Terms: Statistical vs. nonstatistical sampling
Diff: Challenging
Objective: LO 15-1

12) Briefly explain why auditors utilize audit sampling.
Answer: Auditors use sampling techniques primarily because it is generally impractical to
audit all transactions or balances. Consequently, auditors must design strategies to select
items from the population that are likely to be representative of the remaining unaudited
population items. In addition, auditors often use sampling techniques because of
economic realities. That is, clients generally do not want to incur the substantial fees
associated with auditing every transaction or balance.
Terms: Audit sampling

Objective: LO 15-1

13) Discuss what is meant by "sampling risk" and "nonsampling risk".
Answer: Sampling risk occurs when the sample is not representative of the
population; that is, the characteristics of interest in the sample are not the same as
those in the population. Nonsampling risk occurs when audit tests do not uncover
existing exceptions in the sample.
Terms: Sampling and nonsampling risks
