Answer:
C: Reliability level
E: Estimated error rate
H: Maximum tolerable rate
1.The reliability level – this is the probability of being right in placing reliance on an effective internal control accounting system. If the reliability level is 95%, the auditor has only a 5% risk of placing reliance on internal accounting control when the system is ineffective given a certain tolerable rate. After the auditor determines the reliability level, she can then choose the correct sampling table based on this level. “The risk of assessing control risk too low” is the risk that the assessed level of control risk based on the sample is less than the true operating effectiveness of the control.
2.The estimated error rate – this is also referred to as the estimated population occurrence rate (expressed in percentage terms). If the auditor does not know what the estimated error rate is, select a sample of 50 to estimate the population occurrence rate. If two errors were discovered, the estimated error rate would be (2/50), or 4%.
3.The maximum tolerable rate – this is the rate above which the auditor would place less than full reliance on the control being evaluated.
