You are the auditor of Unet Inc., an auto air-conditioner service and repair company, and you have decided to use the mean-per- unit method to test the existence and gross valuation of recorded accounts receivable. The client's records include 10,000 accounts with a total book value of $2,500,000. You decide to use tolerable misstatement of $182,000, an incorrect acceptance risk of 5 percent, and an incorrect rejection risk of 4.6 percent. Using Excel, you estimated the standard deviation of the population as $100. a. Determine the sample size. b. Assume you tested the sample and got the following results: The mean audited value of the accounts in the sample was $244. Assuming that the standard deviation of the sample's audited value is also $100, will you accept the account as not being materially misstated? What is the projected misstatement for the population? c. Assuming that the standard deviation of the sample's audited value is $125, will you accept the account as not being materially misstated? Show your calculations. What is the projected misstatement for the population
