Your manager, Sally, believes that nonstatistical sampling is the best method to use on the audit of YaYa Corporation. You, however, believe that statistical sampling is by far the better method. In addition, you have a great deal of training in the proper use of sampling techniques. Prepare an argument to convince Sally why statistical sampling should be used.

For an attributes sampling plan, the tolerable deviation rate is 4%, the computed upper deviation rate is 7%, the sample deviation rate is 3%, and the risk of assessing control risk too low is 5%. Which of the following is true?

B) The auditor is likely to increase control risk because the risk of assessing control risk too low is greater than the tolerable deviation rate.
C) The auditor must increase control risk because the computed upper deviation rate is greater than the tolerable deviation rate.

An auditor is testing internal control procedures that are evidenced on an entity's vouchers. To select the vouchers for testing, the auditor obtains random numbers between the first and last voucher number in the period. If a random number matches the number of a voided voucher, that voucher ordinarily should be replaced by another voucher in the random sample if the voucher


A) Constitutes a deviation.
B) Has been properly voided.
C) Cannot be located.
D) Represents an immaterial dollar amount.

Harvey Jones, CPA, uses statistical sampling to test control procedures. What is a benefit of using statistical sampling?

B) It eliminates the use of judgment required of Jones because the AICPA has established numerical criteria for this type of testing.
C) It increases Jones' knowledge of the entity's prescribed procedures and their limitations.
D) It is required by generally accepted auditing standards.
