Using the risk of incorrect acceptance, tolerable deviation rate, sample size, and the number of deviations shown below, determine the sample deviation rate, computed upper deviation rate, and the auditor's conclusion (i.e., testing results do or do not support operating effectiveness of the control) for each control procedure. Use Tables 8-8 and 8-9 below for reference.
