An advantage of using statistical over nonstatistical sampling methods in tests of controls is that the statistical methods 1. eliminate the need to apply professional judgment in determining appropriate sample sizes. 2. emphasizes qualitative evaluation of results as opposed to quantitative evaluations. 3. affords greater assurance than a nonstatistical sample of equal size. 4. provides an objective basis for quantitatively evaluating sample risk. b. The diagram below depicts an auditor's computed upper exception rate (CUER) compared with the tolerable exception rate (TER), and also depicts the true population exception rate comp with the TER As a result of tests of controis, the auditor assesses control risk too low and thereby decreases substantive testing. This is ilustrated by which situation? 1. 1 2. 11 3. III 4. IV c, in absessing sampling risk, the risk of underreiance (f.e., the risk of asessing controf risk too high) relates to the 1. efficiency of the avdit. 2. aflectiveness of the audt. 3. audit qualify controls 4. selection of the dems in the sample
