The provided sources strongly support the credibility and context of the statement, even though none explicitly confirms the 4.4% figure. Multiple high-authority sources identify the U.S. Bureau of Economic Analysis (BEA) as the definitive government agency responsible for releasing official GDP data, including revisions. This establishes that the statement refers to a real, verifiable type of data from the correct authority. Furthermore, there is no conflicting evidence. One source cites an earlier GDP estimate of 2.8%, which is consistent with the standard process where initial estimates are later revised. The other numerical data points are either irrelevant (e.g., Industrial Production) or are clearly identified as forecasts, not official revisions. The complete lack of contradiction from the most authoritative sources, combined with evidence that supports the process of GDP revision, builds a strong circumstantial case for the statement's accuracy. The high probability reflects the weight of this consistent, supportive, and non-contradictory evidence.
