Problems (Answer all of these) 1. The auditors are using mean-per unit sampling to evaluate the reasonableness of the book value of the accounts receivable of Mojito, Inc. Mojito has 10,000 receivable accounts with a total book value of $1,000,000. The auditors estimate the population's standard deviation as being equal to $20. 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 4.6% and a risk of incorrect acceptance of 5% should be used. Required: (10 points) a. Calculate the required sample size. b. Now, ignore your sample size calculation in part a. and assume that your answer was a sample size of 150 and that you obtained the following results: Average audited value of items in sample $96 Average book value of items in sample Sample Standard deviation $98 $22 Using mean-per-unit sampling, calculate the projected misstatement for the population. C. Still using a sample size of 150, using mean-per-unit sampling, calculate the adjusted allowance for sampling risk and use it to form a statistical conclusion concerning the book value of the population ($1,000,000). That is, calculate an interval and either "accept" or "reject" the client's book value.
