Deck 17: Audit Sampling for Tests of Details of Balances

Question 1

Both sampling and nonsampling risks are associated with

A)
B)
C)
D)

Answer 1

A

Question 2

You are auditing Raji and Company.You discover an item of inventory with an audited value of $5,000 with a recorded amount of $3,000.If this is the only error you discover,the projected misstatement for the sample would be

A)$5,000.
B)$2,000.
C)$3,000.
D)$4,000.

Answer 2

B

Question 3

The most important difference among tests of controls,substantive tests of transactions,and tests of details of balances lies in what the auditor wants to measure.Explain what each type of test attempts to measure.

Answer 3

Tests of controls focus on testing the operating effectiveness of internal controls.In substantive tests of transactions,the auditor is concerned about both the operating effectiveness of internal controls and the monetary correctness of transactions in the accounting system.In tests of details of balances,the concern is determining whether the dollar amount of an account balance is materially misstated.
