Assume you are planning the confirmation of accounts receivable. There are 2000 customer accounts with a total book value of 5,643,200. Tolerable misstatement is set at $200,000, and expected misstatement is 40,000. The risk of incorrect acceptance is 30%, the ratio of expected to tolerable misstatement is 20%, and the ratio of tolerable misstatement to the population is 3.5% (round down to 3% for use in Exhibit 8.7)

a) What is the sample size?

b) What is the sampling interval?

c) What is the largest value you can use for a random start

d) Using the following list of the first 15 items in your population, a random start of 25,000, and a sample interval of $100,000, identify the items to be included in your sample.

e) What is the probability of selecting each of the following population items, assuming a $100,00 sampling interval?

f) Why might the final sample size include fewer logical unites than the computed sample size?

g) What is the statistical conclusion if no misstatements are found in the sample? Is the account balance acceptable?

Assuming sampling interval of $100,000 and the following findings:

h) Calculate the total estimated misstatement

i) Do these results indicate that the account balance as stated is acceptable?

j) If the results are not acceptable, what courses of action are available to the auditor?
