Chapter 8 TB Flashcards
Audit sampling implies the gathering of evidence to use as a basis for making valid inferences about the characteristics of the population as a whole without examining every transaction.
T or F?
TRUE
Audit sampling is the application of an audit procedure to less than 100 percent of the items within an account balance or class of transactions for the purpose of evaluating some characteristic.
T or F?
TRUE
When performing substantive tests using sampling methods, the auditor’s main concern is the risk of incorrect rejection.
T or F?
FALSE
When performing substantive tests using sampling methods, the auditor’s main concern is the risk of incorrect acceptance.
The risk of incorrect acceptance of an account balance as correct, when in fact it is not correct, bears directly on the effectiveness of an audit.
T or F?
TRUE
The tolerable misstatement is the level of misstatement the auditor expects to detect in the population.
T or F?
FALSE
The expected misstatement is the level of misstatement the auditor expects to detect in the populatio
Statistical sampling is used when an auditor chooses to examine all purchases of equipment exceeding $1,000.00 and to test the remaining items by analytical procedures.
T or F?
FALSE
The most efficient method of testing a large population is the use of nonstatistical sampling.
T or F?
FALSE
The most efficient method of testing a large population is the use of statistical sampling.
Statistical sampling assists auditors in determining the sufficiency of evidence gathered.
T or F?
TRUE
When testing controls, the use of haphazard selection of a sample allows for random, statistical evaluation.
T or F?
FALSE
The tolerable failure rate is the level at which the control’s failure to operate would cause the auditor to conclude that the control is not effective and would likely change the auditor’s planned assessment of control risk in performing tests of account balances.
T or F?
TRUE
The expected population deviation rate is the auditor’s best estimate of the percentage of transactions processed for which a control is not effectively applied.
T or F?
TRUE
An attribute is defined as a characteristic of the population of interest to the auditor.
T or F?
TRUE
The sample size decreases as the risk of overreliance decreases.
T or F?
FALSE
The sample size decreases as the risk of overreliance increases and the confidence level decreases.
For tests of controls, the most commonly used statistical method is attributes sampling.
T or F?
TRUE
Increasing the expected failure rate will cause the sample size to increase.
T or F?
TRUE
Sample size varies directly with sampling risk.
T or F?
FALSE
Sample size varies inversely with sampling risk.
Statistical sampling used in control testing eliminates the need for evaluation of errors from a qualitative perspective.
T or F?
FALSE
- Quantitative evaluation
- Qualitative evaluation
- Linkages of test of controls and substantive analytical procedures
The auditor must define the population to which sampling relates if the auditor is to use statistical sampling for substantive tests of account balances.
T or F?
TRUE
The individual auditable elements defined by the auditor are the sampling units.
T or F?
TRUE
The most common statistical approaches for substantive testing are classical variables sampling and MUS.
T or F?
TRUE
Nonstatistical samples should be based on the same audit considerations as those used for statistical sampling.
T or F?
TRUE
Random sampling can be used even if the auditor does not plan on using statistical sampling.
T or F?
TRUE
Either nonstatistical or statistical sampling is appropriate for substantive tests of details.
T or F?
TRUE
Monetary unit sampling (MUS) is designed to test whether there is an acceptable risk of account balance understatement.
T or F?
FALSE
Monetary unit sampling (MUS) is designed to test whether there is an acceptable risk of account balance overstatement.
Monetary unit sampling (MUS) results in an efficient sample size and concentrates on the dollar value of the account balances.
T or F?
TRUE
Sample size in a MUS sample is a function of risk of incorrect acceptance, tolerable misstatement, and expected misstatement.
T or F?
TRUE
The population for MUS is defined as the number of dollars in the population being tested.
T or F?
TRUE
Sampling risk is defined as the risk that an inference drawn from a sample will be incorrect.
T or F?
TRUE
Projected misstatements are developed by extrapolation from the misstatements in sample items to the population.
T or F?
TRUE
When evaluating an MUS sample, if the auditor finds no misstatements in the sample, the misstatement projection is zero dollars, and the total estimated misstatement will equal the projected misstatement for items in lower-stratum.
T or F?
FALSE
When evaluating an MUS sample, if the auditor finds no misstatements in the sample, the misstatement projection is zero dollars, and the total estimated misstatement will equal the basic precision.
Population items with zero balances have no chance of being selected using PPS sampling.
T or F?
TRUE
Population items with a zero balance have the same chance of being chosen as those with dollar balances when using MUS sampling.
T or F?
FALSE
Evaluating statistical sample results is one of the tasks that can be performed by data analytics tools.
T or F?
TRUE
In sampling for substantive tests of details, the population is a group of items in an account balance that the auditor wants to test.
T or F?
TRUE
Tolerable misstatement is the maximum amount of misstatement the auditor can accept in the population without requiring an audit adjustment or a qualified audit opinion.
T or F?
TRUE
Extracting data from the client’s computer system is one of the tasks that can be performed by data analytics tools.
T or F?
TRUE
Statistical sampling combines the theory of probability and statistical inference with audit judgment and experience.
T or F?
TRUE
An example of attributes testing involves obtaining evidence that the client has matched the vendor invoice details with a purchase order and receiving report before payment approval.
T or F?
TRUE
A sample which exceeds the tolerable rate of deviation results in the auditor’s reliance on internal control effectiveness.
T or F?
FALSE
Attributes sampling for testing controls should only be done by the auditor at the end of the fiscal period under audit.
T or F?
FALSE
In analysis of the results of an attributes sampling plan, an auditor may determine that the sample size must be increased.
T or F?
TRUE
Simple random sampling, systematic sampling, and block sampling are acceptable sample selection methods for statistical sampling.
T or F?
FALSE
