Williams,CPA intends to use probability-proportional-to-size sampling.He has properly selected and audited a sample of 100 accounts receivable from his client's population of 3000 accounts.He calculated a sampling interval of $5,000 and the tolerable misstatement for the account is $40,000.He has the following table available: Williams also recalls that "basic precision" is equal to the appropriate reliability factor multiplied times the sampling interval.He wishes to accept a risk of incorrect acceptance of 10 percent.
He found that 97 of the 100 accounts in the sample were properly calculated.However,the following three errors existed: $$\begin{array} { c c } \text { Book Value } & \text { Audited Value } \\\$ 50 & \$ 49 \\400 & 300 \\8,000 & 6,000\end{array}$$ a.Calculate the projected misstatement.
