B) Variables and attributes.
C) Constants and attributes.
D) Constants and variables.

Assume a mean-per-unit estimation variables sampling application with a tolerable misstatement of $70,000 and a book value of $700,000.After performing the sampling plan,the auditors calculated an adjusted allowance for sampling risk of $45,000 and a point estimate of the population's total audited value to be $650,000.Based on these results,the auditor would:


A) Because the tolerable misstatement exceeds the adjusted allowance for sampling risk, conclude that the population does not contain a material misstatement.
B) Because the total audited value ± tolerable misstatement includes the book value, conclude that the population does not contain a material misstatement.
C) Because the tolerable misstatement exceeds the adjusted allowance for sampling risk, conclude that there is too great a risk that the account balance is materially misstated.
D) Because the total audited value ± adjusted allowance for sampling risk does not include the book value, conclude that there is too great a risk that the account balance is materially misstated.
