What aspect is NOT affected by the average dollar value of check requests in attribute sampling?

1. The number of check requests selected

2. The risk of incorrect acceptance

3. The expected deviation rate

4. The tolerable deviation rate

The correct answer is: The number of check requests selected

In the context of attribute sampling, the average dollar value of check requests typically influences several factors related to the sampling process. However, the number of check requests selected does not directly depend on the average dollar value of the requests. The primary concern in determining how many items to sample is typically the desired level of confidence and precision that the auditor seeks to achieve, along with factors like the expected deviation rate, tolerable deviation rate, and the risk of incorrect acceptance. These factors focus more on the compliance and accuracy of the sample rather than on the dollar value of the items being evaluated. The expected deviation rate refers to the anticipated percentage of deviations in the sample based on historical data and the auditor's judgment. The tolerable deviation rate is the maximum rate of deviation that the auditor can accept while still relying on the control. The risk of incorrect acceptance is the risk that the auditor will conclude that a control is effective when it is, in fact, not effective, which is also unrelated to the dollar value of the check requests. Therefore, the number of check requests selected remains determined primarily by the sampling plan and the attributes being tested, rather than linked to the average dollar value. This is why the correct answer highlights that aspect as unaffected.
