It is important to recognizethat audit sampling may be constructed on a nonstatistical basis. If the auditor usesstatistical sampling, probability theory willbe used to determine sample size and random selection methods to ensure each item or GHc1 in value of the population has the same chance of selection. Non-statistical sampling is more subjective than statistical sampling, typically using haphazard selection methods and placing no reliance on probability theory. However, in certain circumstances statistical sampling techniques maybe difficult to use. The auditor will reviewthe circumstances of each audit before deciding whether to use statistical or non-statistical sampling. Required: (a) List threesituations where the auditor would be unlikely to use audit sampling techniques. (b) Explain what you understandby the following terms: (i) Random sampling; (ii) Monetary unit sampling. (c) Describe the factors which theauditor should consider whendetermining the size of a sample. (d)…
