Question 3

A)Describe three types of sample selection methods commonly associated with statistical audit sampling.B)Explain the difference between sampling with replacement and without replacement.Which method is more common in audit practice?C)Describe the steps involved in systematic sampling.

Accepted Answer

A)Three types of sample selection methods commonly associated with statistical audit sampling are:
•Simple random sample selection.Every possible combination of elements in the population has an equal chance of constituting the sample.
•Systematic sample selection.A probabilistic method of sampling in which the auditor calculates an interval (the population size divided by the number of sample items desired),and selects the items for the sample based on the size of the interval and a randomly selected number between zero and the interval size.
•Probability-proportionate-to-size sample selection.The probability of selecting any individual population item is proportional to its recorded amount.
B)In replacement sampling,an element in the population can be included in the sample more than once,whereas in nonreplacement sampling,an element can be included only once.Nonreplacement sampling is more common in audit practice.
C)In systematic selection,the auditor calculates an interval (the population size divided by the number of sample items desired)called the selection,or skip,interval.The auditor then randomly selects a number between zero and the interval size less one (i.e. ,if the interval equals 20,the random number is selected from 0 to 19).This number is the starting point for the sample selection;i.e. ,the document or transaction corresponding to the random number plus the first number in the population constitutes the first item in the sample.The second sample item is the interval added to the first number (first document number in the population plus the random number);the third item is determined by adding the interval to the second number,the fourth item is determined by adding the interval to the third number,and so on.

Question 5

Accepted Answer

A)  direct (larger TER = larger sample) .

C)  variable (sometimes larger,sometimes smaller) .
D)  not determinable.

Question 6

Which of the following statements is a valid criticism of the use of nonstatistical sampling methods?

Accepted Answer

A)  Many audit tests,such as footing of journals,must be performed outside a statistical sampling context.
B)  The cost of performing random selection or testing often exceeds the benefits.
C)  Nonstatistical sampling does not differ substantially from statistical sampling methods.
D)  It can be difficult to remain unbiased in the selection of items.

Question 7

As part of the audit of sales,the auditor has used attribute sampling to select a sample of sales invoices.The auditor has examined the duplicate sales invoice to determine whether it was approved for credit.The client has a December year end.In October,the auditor conducted the interim audit and drew a sample of 40 items that covered the period from January to September.In order to be able to generalize to the sales population,the auditor should also

Accepted Answer

A)  select sample items from the rest of the year.
B)  increase the sample size in proportion to the total population size.
C)  use statistical methods to calculate sampling risk.
D)  use statistical methods to calculate nonsampling risk.

Question 8

When does the auditor use simple random sampling?

Accepted Answer

A)  when the auditor has particular judgmental criteria that are used to select the sample
B)  where the auditor wants numbers in sequence and would like to select the sample rapidly
C)  for testing of cutoff after the year end with respect to accounts payable
D)  for populations where each item is considered to have the same characteristics for audit purposes

Question 9

In statistical terms,acceptable risk of assessing control risk too low (ARIA)corresponds with

Accepted Answer

A)  sampling risk.
B)  inherent risk.
C)  control risk.
D)  nonsampling risk.

Question 10

Assume that the client's internal controls require a clerk to attach a shipping document to every duplicate sales invoice but this procedure is not followed exactly 3 percent of the time.If the auditor selects a sample of 200 duplicate sales invoices,which of the following sample results is most representative of the population?

D)  number of exceptions in the sample increases.

Question 12

Accepted Answer

A)  a 100% assumption for all errors.
B)  that the actual sample errors are representative of the population errors.
C)  that the population errors are larger than the sample errors.
D)  that the population errors are smaller than the sample errors.

Question 13

You are working on the testing of internal controls over price changes in the inventory system.You completed the controls testing to determine whether all price changes were approved by the senior accountant,by reference to master file change forms.In order to place reliance on this control,your audit supervisor has decided that the error rate in the population should be less than 1%.When you calculated your sample size,you used a confidence level of 90% and predicted an error rate of less than one percent.Based on these decisions,you examined 150 inventory price master file change forms.In your testing you uncovered two deviations.Based on these results,you calculate that the actual error rate in the population could be as high as 2.33%.
Required:A)What actions are available to you regarding your planned reliance on the master file change controls? B)What are the advantages and disadvantages of each action? C)How would you decide which action to take?
