What is the name of the statistical sampling program provided by the OIG?

RAT-STATS, which stands for Random Accuracy Testing Statistical Software, is the statistical sampling program provided by the Office of Inspector General (OIG). It is designed to assist in conducting statistically valid sampling for audit and compliance activities. This tool is particularly significant in the Medicare and Medicaid programs, as it helps auditors create reliable samples that can support conclusions about larger populations, ensuring that audits are efficient and effective.

The other options do not align with the established tools recognized by the OIG. While they may represent hypothetical or commercial tools that could assist with audits or sampling, RAT-STATS is specifically developed for use by the OIG, emphasizing its relevance and authority in this context. This makes it the correct answer for identifying the OIG's statistical sampling program.
