An auditor selects a preliminary sample of 100 items out of a population of 1,000 items. The sample statistics generate an arithmetic mean of \($60\), a standard deviation of \($6\), and a standard error of the mean of \($0.60\). If the sample was adequate for the auditor’s purposes and the auditor’s planned allowance for sampling risk was plus or minus \($1,000\), the minimum acceptable dollar value of the population would be

a. \($61,000\).

b. \($60,000\).

c. \($59,000\).

d. \($58,800\)
