Final answer:
True. Sampling can be used for both tests of controls and substantive tests of account balances and assertions.
Step-by-step explanation:
True. Sampling can be used for both tests of controls and substantive tests of account balances and assertions. When conducting tests of controls, the auditor is assessing the effectiveness of an entity's internal controls, whereas in substantive tests of account balances and assertions, the auditor is evaluating the completeness, accuracy, and validity of the financial statements. Sampling is a statistical technique used to draw conclusions about a population based on a sample taken from that population.
