When you audited Kingston Company’s performance of its control procedures, you found four deviations of “wrong quantity billed” in a sample of 80 invoices. At the risk of assessing control risk too low of 5%, this finding showed a UEL of 12%, which is more than your tolerable rate of 4%. This quantitative evidence indicating control deficiency now subjects you to a risk of assessing control risk too high if you decide internal control risk is high and you should do more audit work on the accounts receivable.

Required:
Calculate the risk of assessing control risk too high based on the presumption that only 4% of invoices in the population actually have billed the wrong quantity to customers.
