Stratified sampling is used when the population can be divided into distinct subgroups (strata) that differ significantly from each other but are internally homogeneous. In the context of auditing, revenue earned through cash receipts or as receivables would have different characteristics and risk profiles. Stratifying the population allows the auditor to ensure that each subgroup is adequately represented in the sample, leading to more reliable and accurate audit conclusions.

The accounting treatment should reflect the actual costs incurred. Training costs are recognized as they are completed, regardless of the delivery status of the aircraft. For the aircraft production, the costs should be accounted for based on the actual production hours completed to date. This ensures that the financial records accurately represent the work performed and the expenses incurred.

The most effective step in helping the auditor determine whether fraud exists after observing a double payment transaction on a supplier invoice is to perform data analytics on the supplier ' s information, invoiced amounts, and payments performed. Data analytics allows the auditor to systematically analyze large volumes of transactions to identify patterns, anomalies, and potential fraudulent activities. This approach is more comprehensive and effective in uncovering fraud than simply extending the audit scope or switching to a fraud investigation engagement without a thorough initial analysis.

In internal auditing, when assessing the accuracy and completeness of employee time reporting, auditors often use sampling to determine the overall compliance of the process. In this scenario, the internal auditor sampled 30 employee time reports and found 5 incorrect and 4 unsupported reports. This indicates that a majority (21 out of 30) were accurate, suggesting that the organization generally ensures accurate reporting. However, the presence of incorrect and unsupported reports indicates deficiencies that need to be addressed, but do not point to systemic fraud or abuse. Thus, option D accurately reflects the findings by acknowledging both the general accuracy and the instances of errors.
