Baily Cox, an audit manager, judged that the test of controls of the company’s 50,000 purchase transactions should be based on a tolerable rate of deviation of 6 percent, a risk of overreliance of 5 percent, and an expected population deviation rate of 3 percent. Using AICPAsample size tables, Cox determined that the appropriate sample size in this situation would bea. 49.b. 78.c. 132.d. 195

In performing a test of controls for ABC, Inc., the auditor wants to know whether Sales order are approved before goods are picked, packed and shipped to customers. The CPAs has stipulated a Tolerable Deviation Rate (TDR) of 8 percent with a Risk of Assessing Control Risk too low of 5 percent. The CPA also anticipates a deviation rate of 2%. What type of sampling plan should the auditor use for this test? Attribute sampling Monetary sampling
Hattab auditing Co. was conducting the audit of Metro market for the fiscal year ended December 31. The auditor decides that MUS is the appropriate sampling technique to use in order to audit Metros’ inventory account. The balance in the inventory at December 31 was $3,000,000. The auditor has established the following: the desired confidence level of 90%, tolerable misstatement $270,500, and expected misstatement $65,500. Requirement: 1- Calculate the sample size and sampling interval. 2- The staff accountant performed the audit procedures listed in the invent+ory audit program for each sample item. Using the sample size computed in requirement (1), calculate the upper limit on misstatement based on the following misstatements.

A CPA company is conducting the audit of Finch Hardware Company for the year ended December 31. The senior-in-charge of the audit plans to use MUS to audit Finch’s inventory account. The balance at December 31 was $9,000,000, tolerable misstatement is $360,000, expected misstatement is $90,000, and the risk of incorrect acceptance is 5%. Compute the required MUS sample size and sampling interval using Table 8-5 in the textbook (round your interval answer to the nearest whole number).
Attributes Sampling with IDEA: Evaluating Sample Results. Based on a population sizeof 388 shipments, a 10 percent desired risk of overreliance, an expected population deviation rate of 1 percent, and a tolerable rate of deviation of 6 percent, the audit team selected asample of 58 items.In performing tests of controls, your audit team identified three shipments that were notsupported by an approved sales order and concluded that these represent deviations from thecontrol activity.Required:a. Use IDEA to determine the ULRD. What would the audit team’s conclusion be withrespect to the functioning of ELM’s control over the authorization of sales transactions?Part (b) is a set of independent scenarios that affect the evaluation of sample results.b. For each of the following numbers of deviations, use IDEA to determine the ULRD andprovide the audit team’s conclusion with respect to the functioning of ELM’s controlover the authorization of sales transactions.1. 0 deviations.2. 1…
Kendall Jackson, CPA, is examining the operating effectiveness of the internal control of Town Mo, a large conglomerate in the music industry. As partof the evaluation, Jackson determined a necessary sample size of 93 items (based on a tolerable rate of deviation of 5 percent, an expected population deviation rate of 0.5 percent, anda risk of overreliance of 5 percent). After properly selecting the 93 items, Jackson found nodeviations from the prescribed control activities.Required:a. Based on Jackson’s sample, determine the sample rate of deviation and ULRD. (Becausethe AICPA sample evaluation tables do not contain a row for a sample size of 93, rounddown and use a sample size of 90.)b. Explain the difference between the ULRD and the sample rate of deviation observed in part(a). How does this difference relate to the use of statistical sampling?c. What would Jackson conclude with respect to the operating effectiveness of Town Mo’sinternal control?
In an MUS sample with a sampling interval of $5,000, an auditor discovered that aselected accounts receivable with a recorded amount of $10,000 had an audit valueof $8,000. If this is the only error discovered by the auditor, the projected error ofthe sample would be(1) $1,000. (3) $4,000.(2) $2,000. (4) $5,000.
Evan Kristopher, CPA intends to use probability-proportional-to-size sampling. He has properly selected and audited a sample of 100 accounts receivable from his client’s population of 3,000 accounts. He calculated a sampling interval of $6,000 and the tolerable misstatement for the account is $30,000. Evan also recalls that “basic precision” is equal to the appropriate reliability factor multiplied times the sampling interval. He wishes to accept a risk of incorrect acceptance of 10%. He found that 97 of the 100 accounts in the sample were properly calculated. However, the following three errors existed: Book Value Audited Value $75 $70 1,000 750 9,300 6,720 Required: Calculate the projected misstatement. Calculate the basic precision. Calculate the incremental allowance. Calculate the upper limit on misstatement. What would the auditors’ conclusion be for the population based on the analysis? explain please

d. Assume that based on additional controls implemented by ELM, your audit team has decided to reduce the expected misstatement from $77,928 to $19,482 (0.5 percent of the recorded balance of the transactions). What is the necessary sample size, holding all other factors constant?

Carson Allister is performing a PPS application in the audit of Bird Company’s accounts receivable. Based on the acceptable level of the risk of incorrect acceptance of 5 percent and a tolerable misstatement of $120,000, Allister has calculated a sample size of 75 items and a sampling interval of $25,000. After examining the sample items, the following misstatements were identified: (Use Exhibit F.A.2.) Item Recorded Balance Audited Value 1 $35,000 $28,000 2 10,000 8,000 3 6,000 3,000 Required: Calculate the upper limit on misstatements for Bird Company’s accounts receivable.
An audit firm is conducting the audit of Diaz Construction Company for the fiscal year ended October 31. Rebecca Smith, the partner in charge of the audit, decides that MUS is the appropriate sampling technique to use in order to audit Diaz’s inventory account. The balance in the inventory at October 31 was $4,250,000. Rebecca has established the following: risk of incorrect acceptance = 5% (i.e., the desired confidence level of 95%), tolerable misstatement = $212,500, and expected misstatement = $63,750. Calculate the sample size and sampling interval using Table 8-5 in the textbook (round your interval answer to the nearest whole number).
