True or False: Write the word TRUE if the statement is true, and the word FALSE if the statement is false.

________1. The professional standards require the auditor to obtain sufficient appropriate evidence to be able to draw reasonable conclusions on which to base an audit opinion. ________2. The auditor may decide that it would be more appropriate to examine the entire population (100% examination) of items that make up an account balance since the population constitutes a small number of large value items. ________3. Regardless of the approach used, the auditor needs to be satisfied that sufficient appropriate evidence is obtained to meet the objectives of the test. ________4. The Beta risk affects the audit effectiveness. ________5. The Alpha risk affects the audit efficiency. ________6. Sampling risk refers to the risk that the auditor may draw incorrect conclusions about the account balance or class of transactions because of human error. ________7. There is no way to eliminate sampling risk. ________8. The first step in audit sampling is determining the audit procedures to be performed. ________9. Audit sampling for substantive tests is generally appropriate when application of the control leaves evidence to performance. ________10. Auditors usually draw conclusions about the account balance or transaction class by examining the entire population.

13. Which statement is incorrect regarding factors affecting sample size for substantive tests? a. The lower the tolerable misstatement, the larger the sample size needs to be. b. The greater the amount of misstatement the auditor expects to find in the population, the larger the sample size needs to be. c. The more audit evidence that is obtained from test of details, the larger the sample size will need to be. d. The greater the level of assurance that the auditor requires that the results of the sample are in fact indicative of the actual amount of misstatement in the population, the smaller the sample size needs to be. 14. Given: Overall audit risk: 5% Inherent risk: 100% Control risk: 80% Risk of analytical procedures not detecting a misstatement: 60%

The risk of incorrect acceptance is a. 10% b. 20%

c. 30%

d. 40%

15. I. The lower the risk the auditor is willing to accept, the greater the sample size will need to be. II. The sample size can be determined by the application of a statistically-based formula or through the exercise of professional judgment objectively applied to the circumstances. a. b. c. d.

true; true true; false false; true false; false

16. In using ratio and difference estimation techniques, the following are required except: a. Book value of population item b. Audited value for each sample item c. Ratio between the audited and book values d. Differences between the audited and book values 17. Choose the incorrect statement/s: I. When the average misstatement is nearly proportional to the book value of the items, the use of ratio estimation is appropriate because large accounts have large misstatements and small accounts have small misstatements. II. In evaluating the sample results, the auditors also project the misstatements found in the sample to the population and consider sampling risk, the level of risk is quantified. III. When a projected misstatement indicates an overstatement, the difference is subtracted from the book value, when a projected misstatement indicates an understatement; the difference is added to the book value. a. b. c. d.

I only I and II I, II, III all statements are correct
