Please help me solve this. Subject: Internal Auditing

ABC Company processes on average 700 vouchers payable every month. Each voucher package contains a copy of the check disbursed and supporting documents such as vendor invoices, receiving reports, and purchase orders. The internal auditor plans to examine a sample of vouchers listed in the voucher register using attribute sampling to evaluate the effectiveness of several controls: The attributes of interest include: 1. Agreement of voucher amounts with invoice amounts. 2. Voucher contains proper authorizations based on amount of the voucher. 3. Voucher canceled after payment. Assume that the auditor's tests uncovered two occurrences of voucher amounts not agreeing with invoice amounts, one occurrence of improper authorization, and two occurrences of vouchers not being canceled after payment. 1. Complete the following table. (Note: round sample size per table up to the next number ending in zero for sample size used.) Attribute 1 Attribute 2 Attribute 3 Risk of assessing control risk too low 5% 5% 5% Tolerable deviation rate 7% 5% 6% Expected population deviation rate 2% 1% 1% Sample size per table Sample size used Number of deviations identified Sample deviation rate Achieved upper deviation limit per table Evaluate the sample results and state the audit decision you would make based on the quantitative sample results for each of the three attributes tested
