QUESTION 3 - AUDIT SAMPLING (20 MARKS) (Suggested Time: 36 Minutes) PART A: SAMPLING APPROPRIATENESS (5 marks) An Audit Assistant made the following conclusion about the work performed during the course of an audit. 1. The Assistant selected a sample of 30%% of the trade creditors' balances to verify the audit assertion of completeness. All balances selected were traced to supporting documentation and no discrepancies were found. The following conclusion was noted: No discrepancies found from testing performed; trade creditor is fairly stated. 2. The Assistant performed a test of controls on purchases. Of a sample of 50 purchases, 4 purchases did not comply with the control procedures as laid down. This gave a sample deviation rate of 8%. The following conclusion was noted: The deviation rate of 8% is below the level of 10% defined to be material in the accounting standards. Therefore, controls over purchases can be relied upon. (Adopted from Leung et al. 2011, p.568) Required: Evaluate the appropriateness of the Assistant's samples and evaluation of the sampling results
