Question 6

When performing a test of a control over cash disbursements, a CPA may use a systematic sampling technique with a start at any randomly selected item. The biggest disadvantage of this type of sampling is that the items in the population:

B)   May occur in a systematic pattern and destroy the sample randomness.
C)   May systematically occur more than once in the sample.
D)   Must be systematically replaced in the population after sampling.

B)   Remain the same.
C)   Decrease.
D)   Indeterminate, depends upon exact change being made.

Question 8

The 3,000 accounts receivable of DEF Company have a total book value of $60,000. Bob Smith, CPA, has selected and audited a sample of 100 accounts with a total book value of $2,100.

Accepted Answer

A)   $1,700
B)   $1,800
C)   $1,900
D)   $2,300

Question 9

During the final planning of the accounts receivable plan a CPA specified a tolerable misstatement of $30,000, instead of the $20,000 contained in the preliminary audit plan. What would be the impact of this change?

Accepted Answer

A)   A decrease in population standard deviation.
B)   An increase in sample standard deviation.
C)   An increase in required sample size.
D)   A decrease in the required sample size.

Question 10

B)   Standard deviation.
C)   Standard error of the sample mean.
D)   Estimated population total minus the actual population total.

Question 11

If all other factors specified in an attributes sampling plan remain constant, changing the specified tolerable rate from 6% to 10%, and changing the specified risk of assessing control risk too low from 3% to 7% would cause the required sample size to:

Accepted Answer

A)   Increase.
B)   Remain the same.
C)   Decrease.
D)   Change by 4%.

Question 12

In variables estimation sampling, the sample standard deviation is used to calculate the:

Accepted Answer

A)   Point estimate of central tendency.
B)   Tainting of the sample interval.
C)   Risk of incorrect acceptance.
D)   Adjusted allowance for sampling risk.

Question 13

Using the mean-per-unit estimation technique, Rotter's estimate (to the nearest dollar) of year-end accounts receivable balance would be:

Accepted Answer

A)   $37,500
B)   $38,462
C)   $38,500
D)   $41,600

Question 14

The auditors expect a population deviation rate of billing errors of two percent, and have established a tolerable rate of five percent. The sampling approach most likely to be used is:

Accepted Answer

A)   Attributes sampling.
B)   Stratified sequential sampling.
C)   Discovery sampling.
D)   None, as sampling does not seem appropriate in this situation.

Question 15
