A

In attribute sampling, a 10% change in which of the following factors normally will have the least effect on the size of a statistical sample? a. populations size b. precision (confidence interval) c. reliably (confidence level) d. standard deviation

A

While performing a test of details during an audit, the auditor determined that the sample results supported the conclusion that the recorded account balance was materially misstated. It was, in fact, not materially misstated. This situation illustrates the risk of a. incorrect rejection b. incorrect acceptance c. overreliance d. under reliance

A

A CPA's client wishes to determine inventory shrinkage by weighing a sample of inventory items. If a stratified random sample is to be drawn, the strata should be identified in such a way that a. the overall population is dividends into subpopulations of equal size so that each subpopulation can be given equal weight when estimates are made. b. each stratum differs as much as possible with respect to expected shrinkage, but the shrinkages expected for items within each stratum are as close as possible c. the sample means and standard deviation of each individual stratum will be equal to the means and standard deviations of all other strata d. the items in each stratum will follow a normal distribution so that probability theory can be used in making inferences from the sample data

B

B

Which of the following sample planning factors would influence the sample size for a substantive test of details for a specific account?

Both the expected amount of misstatements and measure of tolerable misstatement

An auditor plans to examine a sample of 20 purchase orders for proper approvals as prescribed by the client's internal control. One of the purchase orders in the chosen sample of 20 cannot be found, and the auditor is unable to use alternative procedures to test whether that purchase order was properly approved. The auditor should a. choose another purchase order to replace the missing purchase order in the sample b. consider this test of controls invalid and proceed with substantive procedures because internal control is ineffective c. treat the missing purchase order as a deviation for the purpose of evaluating the sample d. select a completely new set of 20 purchase orders

C

As a result of sampling procedures applied as tests of controls, an auditor incorrectly assesses control risk lower than appropriate. The most likely explanation for this situation is that a. the deviation rates of both the auditor's sample and the population exceed the tolerable rate b. the deviation rates of both the auditor's sample and the population are less than the tolerable rate c. the deviation rate in the auditor's sample is less than the tolerable rate, but the deviation rate in the population exceeds the tolerable rate d. the deviation rate in the auditor's sample exceeds the tolerable rate, but the deviation rate in the population is less than the tolerable rate

C

When planning a sample for a substantive test of details, an auditor should consider tolerable misstatement for the sample.

D

An advantage of statistical sampling over nonstatistical sampling is that statistical sampling helps an auditor to a. minimize the failure to detect errors and fraud b. eliminate the risk of nonsampling errors c. reduce the level of audit risk and materiality to a relatively low amount d. measure the sufficiency of the evidence obtained

D

For which of the following audit tests would an auditor most likely use attribute sampling? a. making an independent estimate of the amount of a LIFO inventory b. examining invoices in support of the measurement of fixed asset additions c. selecting accounts receivable for confirmation of account balances d. inspecting employee time cards for proper approval by supervisors

D

In addition to evaluating the frequency of deviations in tests of controls, an auditor should also consider certain qualitative aspects of the deviations. The auditor most likely would give broader consideration to the implications of a deviation if it was a. the only deviation discovered in the sample b. identical to a deviation discovered during the prior year's adults c. caused by an employee's misunderstanding of instructions d. initially concealed by a forged document

D

In performing tests of controls over authorization of cash disbursements, which of the following statistical sampling methods would be the most appropriate? a. variables b. stratified c. ratio d. attributes

D

A benefit of non statistical sampling as compared to statistical sampling is that the sample size can be significantly smaller, thereby making the audit more efficient.

F

A benefit of statistical sampling as compared to non-statistical sampling is that less auditor judgement is required because the auditor can leverage the power of probability theory.

F

Benford's Law helps predict frequency patterns f deviations control

F

In attributes sampling, the attribute of interest is an individual dollar amount in the population.

F

Projected errors for items in the top stratum equal basic precision multiplied by a confidence factor

F

The projected misstatement for items in the upper stratum is calculated as the sampling interval multiplied by the tainting percentage

F

The risk of incorrect acceptance of internal control reliability is the risk that the auditor will conclude that the state of internal controls is not effective when internal controls are actually effective.

F

Top-stratum items are population items whose book values exceed the sampling interval and are therefore excluded from the sample

F

when the auditor detects control deviations, it is best to evaluate them quantitively rather than qualitively

F

haphazard sampling is a statistical sample selection method that attempts to approximate a random selection by selecting sampling units without any conscious bias, or special reason for including or omitting certain items from the sample

F; nonstatistical

When using nonstatistical sampling, the auditor cannot quantitatively assess the risk of making an incorrect inference based on the sample results

T

An auditor should consider the tolerable rate of deviation when determining the number of check requests to select for a test to obtain assurance that all check requests have been properly authorized. The auditor should also consider

No average dollar value of the check requests and yes allowable risk of overreliance

Attributes sampling is a statistical sampling method used to estimate the rate of control procedure failures based on selecting one sample and performing the appropriate audit procedure.

T

Block sampling involves selecting a sample that consists of contiguous population items, such as selecting transactions by day or week.

T

Data analytics is a broad construct referring to both qualitative and quantitative analysis tools that enable a decision maker to extract data, categorize it, identify patterns within it, and use it to enhance efficiency and effectiveness in decision making

T

One strength of MUS is that it automatically selects a sample in proportion to an item's dollar amount, thus providing automatic stratification of the sample.

T

Sampling risk is the risk that the auditor's conclusion based on a sample might be different from the conclusion that would be reached if the audit procedure were applied in the same way to the entire population.

T

The division of a population into two or more subgroups is referred to as stratification

T

The population for MUS is defined as the number of dollars in the population being tested. Each dollar in the population has an equal chance of being chosen, but each dollar chosen is associated with a tangible item such as a customer's balance or an inventory item, so items with more dollars have a greater likelihood of being selected.

T

The diagram depicts the auditor's estimated maximum deviation rate compared with the tolerable deviation rate and also depicts the true population deviation rate compared with the tolerable deviation rate. As a result of testing controls, the auditor under relies on the controls and increases substantive testing. This is illustrated by

The risk of under reliance is one aspect of sampling risk in testing controls
