| "question": "In 2022, there was a view that government subsidies and revenue are clearly correlated among large-asset-scale enterprises in the food and beverage industry. Therefore, researchers sampled the top one-third of large enterprises ranked (rounded down) by total assets as the research subject. What is the Pearson correlation coefficient between government subsidy amount and year-over-year revenue growth rate?", |
| "guidelines": "Answer format: numerical value (retain 4 decimal places). If relevant data cannot be found, please answer \"No relevant data found\"", |
