The audit assistant's conclusion regarding the cash receipt controls is not correct. Although the errors found were immaterial and corrected, the fact that there were errors indicates that the controls may not be working satisfactorily. The tolerable rate of deviation for this test, as per the audit plan, is 5 percent, and the findings exceeded this threshold with a deviation rate of 6.67 percent (4 errors out of 60 transactions).
Therefore, the audit assistant should not conclude that the cash receipt controls are working satisfactorily based on this test. Instead, further investigation and testing should be conducted to determine the root causes of the errors and to evaluate the effectiveness of the controls. This could involve selecting a larger sample size, conducting additional tests, and assessing the overall control environment in the cash receipts area to ensure that risks are adequately mitigated. The conclusion should be based on sufficient appropriate audit evidence rather than solely on the immateriality of the errors.
