17、ms: Statistical vs. nonstatistical samplingDiff: ChallengingObjective: LO 15-1AACSB: Reflective thinking skills12) Briefly explain why auditors utilize audit sampling.Answer: Auditors use sampling techniques primarily because it is generally impractical to audit all transactions or balances. Consequ
18、ently, 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 substant

20、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 risksDiff: EasyObjective: LO 15-1AACSB: Reflective thinking skills14) Discuss what i

Also discuss ways the auditor can control nons
22、ampling risk.Answer: The two causes of nonsampling risk are (1) the auditors failure to recognize exceptions and (2) inappropriate or ineffective audit procedures. The auditor can control nonsampling risk through careful design of audit procedures and through proper instruction, supervision, and rev
