澳洲代筆案例:operations assignment代寫
(a) Describe the population(s) that would be relevant to Bob’s sample selection.
(b) Which sample selection methods would be appropriate for choosing sales invoices for substantive testing at RGHF? Explain the factors that would influence your choice.

(a) Bob is conducting substantive testing of sales invoices. In order to gather evidence about existence, Bob would need to sample the entries in the sales journal and then vouch to the underlying documents. This would also allow evidence to be gathered about the details of the sales transactions that is relevant to the accuracy, classification and cut-off assertions.
In order to gather evidence about completeness of the accounting records, Bob would sample the invoices, and then trace the details of the transactions to the sales journal. This would also provide evidence relevant to the accuracy, classification and cut-off assertions. In this case, Bob has to be careful about which invoices he samples. The conditions in which the boxes of sales invoices are stored appear to be unsatisfactory. He will have difficulty identifying the boxes of sales invoices relevant to the current year. He will also have to be careful not just to sample the invoices that are in boxes near the door or otherwise easy to access, because this would introduce bias to his sampling and potentially invalidate his conclusions.

(b) As noted above, there is an issue about identifying and accessing the sales invoices because of the unsatisfactory conditions in the storage shed. Other information relevant to sampling is the difficulties in the administration department. There have been periods of staff shortages. The auditor should consider stratifying the sample and making sure that they sample from the periods where staff conditions were different. This would provide evidence about the effectiveness of controls under different conditions. The auditor would consider the patterns in customer complaints – do they relate to specific periods, or specific types of sales? Do the complaints suggest greater risk would apply to different parts of the year? Overall, controls over sales invoices appear to be poor and substantive testing should be extensive.


6.5 Determining sample size for control testing
    Required
<标题> Explain how the factors mentioned above would impact on the sample size for control testing of accounts payable.

The number of accounts payable has increased by 50 per cent since last year. An increase in the population has a negligible effect on sample size.
Bunns and Major has changed some of its suppliers. This changes the conditions affecting accounts payable because the change has been from large corporate wholesalers to direct dealing with manufacturers. There is a possibility that the two groups of suppliers would have different levels of quality control over their supplier statements. The auditor would need to consider if there was a decrease (increase) in quality, and if so, increase (decrease) the sample size because there is potentially a greater (lower) degree of error in the supplier statements (an increase/decrease in the expected rate of deviation of the population to be tested).
Belief that controls in accounts payable are likely to be operating more effectively than in previous years because of additional staff, expecting a reduction in control deviations. An expected reduction in control deviation leads to a lower sample size.
A lower tolerable rate of deviation because of the increased importance of accounts payable to the solvency analysis would lead to an increased sample size for control testing.
An increased reliance on controls to justify less substantive testing means that the sample size for control testing will increase (an increase in the extent to which the auditor’s risk assessment takes into account relevant controls leads to increase in sample size).
