Using statistical sampling to assist in verifying the year-end accounts payable balance, an auditor has accumulated the following data: (Population/Sample)
Number of Accounts: 4,100/200
Book Balance: $5,000,000/$250,000
Balance Determined by the Auditor: ?/$300,000
Using the ratio estimation technique, the auditor's estimate of the year-end accounts payable balance would be
33.Which of the following sampling methodswould be used to estimate a numericalmeasurement of a population, such as a pesovalue? A. Variable samplingB.Attribute samplingC.Random-number samplingD. Stop-or-go samplingA. variable sampling plan is designed to test whetheran account balance is materially misstated andtherefore addresses numerical measurements suchas a peso value.Answer Bis incorrect because attribute samplingdealswithdeviationrates,notnumericalmeasurements.Answer Cis incorrect because random-number sampling is a selection method andmay be used with either an attribute or avariable sampling plan.Answer Dis incorrect because stop-or-go sampling(also called sequential sampling) is a form ofattribute sampling.
In stop-or-go sampling, the sample isselected in several steps (i.e., not only asingle sample is tested). For each step, theauditor decided whether to stop the test orto proceed to the next step.35. Which of the following combinations results in adecrease in sample size in an attribute sample?
