The following information concerning one of the prescribed controls has been accumulated: Estimated number of transactions per year 5,000 Risk of assessing control risk too low 5.0% Tolerable deviation rate 4.0% Expected population deviation rate 0.5% Sample size per table 117 Sample size used 125 2. Number of deviations found Sample deviation rate 1.6% Upper deviation limit 4.9% Allowance for sampling risk 3.3% which of the follows should be the statistical conclusion from evaluation of above sample results? Select one: a. The auditor is 96% confident that the true, but unknown, population deviation rate is less than 3.3% b. The auditor is 95% confident that the true, but unknown, population deviation rate is less than 4.9% c. There is a 5% risk that the true, but unknown, population deviation rate is greater than 1.6% d. There is a 95% risk that the true, but unknown, population deviation rate is greater than 4.9%
