Answer to Problem 9.23P
Sample size = 156
Explanation of Solution
Tolerable misstatement :$360,000
Expected misstatement :$90,000
Desired confidence level :95%
Recorded amount of accounts receivable: $9,000,000
Computation of Sample size:

Answer to Problem 9.23P
UML for misstatement:
- $43,269
- $32,365
- $86,538
- $16,153
Explanation of Solution
To calculate UML first sampling interval is required
Tolerable misstatement :$360,000
Expected misstatement :$90,000
Desired confidence level :95%
Recorded amount of accounts receivable : $9,000,000
Sample size :156
Sampling interval :$57,692
Computation of UML:
Computation of tainting factor:
| misstatements | Book value | Audit value | Difference | Tainting factorDifference ÷ book value |
| 1 | $10,000 | $7,500 | $2,500 | 0.25 |
| 2 | 9,000 | 6,000 | 3,000 | 0.33 |
| 3 | 60,000 | 0 | 60,000 | 1 |
| 4 | 800 | 640 | 160 | 0.2 |
Computation of Upper Misstatement limit:
| Misstatement | Tainting Factor1 | Sampling interval2 | Projected Misstatement3(1 × 2) | 95% Misstatement Factor. 4 | UML5(3 × 4) |
| 1 | 0.25 | $57,692 | $14,423 | 3 | $43,269 |
| 2 | 0.33 | 57,692 | 19,038 | 1.7 | 32,365 |
| 3 | 1 | 57,692 | 57,692 | 1.5 | 86,538 |
| 4 | 0.2 | 57,692 | 11,538 | 1.4 | 16,153 |
| Total | $102,691 | $178,325 |
The conclusion of whether inventory account balance is materially misstated is made by comparing the tolerable misstatement to the UML. As UML is $178,325 and it is less than the tolerable misstatement of $360,000, it can be concluded that the account balance is not materially misstated.

The net projected population misstatement.
c
Answer to Problem 9.23P
Projected population misstatement is $6,750,000
Explanation of Solution
The projected population misstatement can be calculated by computing ratio of misstatements to total dollars sampled that is
| misstatements | Book value | Audit value | Difference |
| 1 | $10,000 | $7,500 | $2,500 |
| 2 | 9,000 | 6,000 | 3,000 |
| 3 | 60,000 | 0 | 60,000 |
| 4 | 800 | 640 | 160 |
| 5 | 6,000 | 6,500 | -500 |
| 6 | 750 | 800 | -50 |
| Total | 86,550 | 65,110 |

- The 1,000 accounts receivable of Gamco Company have a total book value of $20,000. Wilbur Schneitz, Certified Public Accountant (CPA), has selected and audited a sample of 50 accounts with a total book value of $900. Using nonstatistical variables sampling and the difference estimation technique, Smith has properly estimated a projected misstatement of an overstatement of $3,000 for the entire population. The total audited value of Schneitz’s sample is: 650 1000 750 900arrow_forwardThe audit staff assigned to audit Maintenance Expenses totaling $4,900,000 selected a sample oftransactions for substantive testing.

There are 100 sales transactions made by the company. Overall of the 100 transactions, according to auditor’s professional judgment, materiality is set at 5% or 5 transactions. The auditor took a sample of 20 transactions, and it turns out that of the 20 transactions examined, there were 2 misstatement found. Based on the results of the sampling inspection, the auditor concluded that there was 2 out of 20 means 10%, and judge this finding as material misstatement. When in fact, overall of the 100 transactions there were only that 2 transactions occurred irregularities or errors that accidentally that two were chosen on 20 random sampling.
