With regard to sampling it can be said that:
A. sampling is generally applicable when the population
relates to an intangible or undocumented control.
B. if an auditor knows internal controls are strong, the
confidence coefficient may be lowered.
C. attribute sampling would help prevent excessive sampling
of an attribute by stopping an audit test at the earliest
possible moment.
D. variable sampling is a technique to estimate the rate of
occurrence of a given control or set of related controls.
Answer / guest
Answer: B
Statistical sampling quantifies how closely the sample
should represent the population, usually as a percentage. If
the auditor knows internal controls are strong, the
confidence coefficient may be lowered. Sampling generally is
applicable when the population relates to a tangible or
documented control. Choice C is a description of stop-or-go
sampling. Choice D is a definition of attribute sampling.
