Exercise 399

Using AICPA sample evaluation tables, determine the conclusion from a statistical sample of internal controls when a sample of 125 documents indicates five deviations if the tolerable rate of deviation is 5 percent, the expected population deviation rate is 2 percent, and the allowance for sampling risk is 3 percent.
A) Accept the evidence as support for assessing a low control risk because the tolerable rate of deviation less the allowance for sampling risk is less than the expected population deviation rate.
B) Use the evidence to assess a higher control risk than planned because the sample rate of deviation plus the allowance for sampling risk exceeds the tolerable rate of deviation.
C) Use the evidence to assess a higher control risk than planned because tolerable rate of deviation plus the allowance for sampling risk exceeds the expected population deviation rate.
D) Accept the evidence as support for assessing a low control risk because the sample rate of deviation plus the allowance for sampling risk exceeds the tolerable rate of deviation.
