Bill Jones wishes to use nonstatistical sampling to select a sample of his client’s 3,000 accounts receivable, which total $330,000. He believes that $30,000 represents a reasonable tolerable misstatement. He also has assessed both the combination of inherent and control risk at the maximum level and the risk that other substantive procedures will fail to detect a material misstatement at the maximum. He wishes to use a structured approach. Use the formula presented in the text to calculate the required sample size.
