*** I need help with the Nonstatistical Evaluation of Errors and Statistical Evaluation of Errors Using the IDEA Monetary Unit Sampling ***

Required information

In this mini-case you will complete the test of details on accounts receivable for the 2016 audit of EarthWear Clothiers, Inc. The principal test of detail involves sending "confirmations" or letters to customers so that they can confirm that they owe EarthWear the reported balance. All six customer accounts receivable balances exceeding $100,000 were targeted for testing. These six balances, aggregated total of $921,000, were confirmed without exceptions. The remaining accounts are of similar size and total $7,722,000 and will be tested via audit sampling. Inputs for the sample size determination were, Desired Confidence Level95%, Tolerable Misstatement$600,000, and Expected Misstatement$154,440. Based on these inputs, 67 accounts receivable balances were selected for confirmation requests. The first 63 accounts receivable confirmations have already been reviewed by other staff members and no errors have been found. The remaining four confirmations require your review as they were returned with notes from customers indicating a potential misstatement. Please note that legitimate timing differences do not result in misstatements.

1. Review the four confirmation responses in the PDF file downloaded from the mini-case website (a link is also provided below). Enter the information into Work Paper 10-1. For each confirmation response, please determine whether the difference noted by the customer represents a misstatement or a timing difference. After reviewing all four confirmations, please complete both the nonstatistical and the statistical evaluation options outlined on Work Paper 10-1 unless your instructor tells you otherwise. Chapter 9 of the text provides guidance on both nonstatistical and statistical evaluation. Please refer to Chapter 9 for a description of how to calculate a sample size and evaluate errors using IDEA. Please be careful as you enter your results from IDEA to the work paper as the items may not be listed in the same order.

Complete the worksheet below by reviewing the accounts receivable confirmation file contained in the Instructions. (Leave no cell blank - Be sure to enter "0" wherever required.)
