Revise the assessed control risk as well as communicate with the audit C Systematic sample selection - select items from the sample based on the size of the interval. To determine this you would divi Example: Sales invoice ranging from 652-3151 With a desired sample size of 125 Your interval would be 20 [(3151-651)/125] D (1500/230,000) *6900, 000= 44,999.73 overstatement. Since if you round to 45 thousand it would fall below the auditor's tolerable misstatements of 150,000. The population would b mmunicate with the audit committee or management. rmine this you would divide the population size by the desired sample size. 0. The population would be fairly stated.
