In Smith, Inc., Rachel Robertson wishes to use mean-per-unit sampling to evaluate the reasonableness of the book value of the accounts receivable of Smith, Inc. Smith has 11,400 receivable accounts with a total book value of $1,590,000. Robertson estimates the population's standard deviation to be equal to $22. After examining the overall audit plan, the auditors believe that the account's tolerable misstatement is $60,000, and that a risk of incorrect rejection of 1 percent and a risk of incorrect acceptance of 5 percent are appropriate. Use Figure 9.8. (Do not round any division. Round other computations and the final answers to the nearest whole value.)
Calculate the required sample size. (Roundup your final answer to the next whole number.) |
Assuming the following results: | |
Book value of items in sample = $145 | |
Average audited value of items in sample = $136 | |
Standard deviation of sample = $24 |
b. | Use the mean-per-unit method to: |
(1) | Calculate the point estimate of the account's audited value. |
Calculate the projected misstatement for the population.
