An auditor is determining the appropriate sample size for testinginventory valuation using MUS. The population has 2,620 inventory items valued at$12,625,000. The tolerable misstatement is $500,000 at a 10% ARIA. No misstatementsare expected in the population. Calculate the preliminary sample size
Evaluating Results: Classical Variables Sampling. Kyle Berry is using mean-per-unit estimation in the audit of Leonard’s inventory balances. Leonard’s inventory is recorded at $240,000 and comprises 1,200 different items. Berry determined a sample size of 120 items and performed the appropriate substantive procedures. Based on this sample, he determined the following:
Average audited value (per item)
$204
Standard deviation of audited values
$ 22
A summary of some additional parameters estimated by Berry follow:
Tolerable misstatement
$ 17,500
Expected misstatement
$ 7,500
Risk of incorrect acceptance
5%
Risk of incorrect rejection

You completed the controis testing to determine whether all price changes were approved by the senior accountant, by reference to master file change forms. In order to place reliance on this control, your audit supervisor has decided that the error rate in the population should be less than 1%. When you calculated your sample size, you used a confidence level of 90% and predicted an error rate of less than one percent. Based on these decisions, you examined 150 inventory price master file change forms. In your testing, you uncovered two deviations. Based on these results, you calculate that the actual error rate in the population could be as high as 2.33%. Required: A.
