D)The population has a high total dollar value.

Question 21

The auditors of Smith Electronics wish to limit the audit risk of material misstatement in the test of accounts receivable to 5 percent.They believe that inherent risk is 100%,there is a 40 percent risk that material misstatement could have bypassed the client's system of internal control,and a 50 percent risk that any existing material misstatement would not have been brought to light by the auditors' analytical procedures.What is the maximum risk of incorrect acceptance the auditors should specify in their substantive tests of details of accounts receivable?

A)5 percent.
B)10 percent.
C)20 percent.
D)25 percent.

Question 22

Williams,CPA intends to use probability-proportional-to-size sampling.He has properly selected and audited a sample of 100 accounts receivable from his client's population of 3000 accounts.He calculated a sampling interval of $5,000 and the tolerable misstatement for the account is $40,000.He has the following table available: Williams also recalls that "basic precision" is equal to the appropriate reliability factor multiplied times the sampling interval.He wishes to accept a risk of incorrect acceptance of 10 percent.
He found that 97 of the 100 accounts in the sample were properly calculated.However,the following three errors existed: a.Calculate the projected misstatement.
b.Calculate the basic precision.
c.Calculate the incremental allowance.
d.Calculate the upper limit on misstatement.
e.Explain how the auditors would consider the results calculated above.

B)There is a low expected misstatement rate in the population.

D)The book value of the population is large.

Question 24

Which statement is correct with respect to the probability-proportional-to-size technique?

A)The technique insures that every account in the population has an equal chance of being selected.
B)The technique automatically stratifies the population.
C)The technique results in a representative sample every time.
D)The technique allows the auditors to measure more precisely the risk of incorrect acceptance.
