Save your output file(s) under `/app/output`. Conduct a two-sample t-test to evaluate whether there is a significant difference in the natural log of total medals between countries that host the Olympics and those that do not. Based on a p-value threshold of 0.05, determine the conclusion: "Same distributions (fail to reject H0)" or "Different distributions (reject H0)". Present your findings as follows: """ { "T-Statistics": [...], "P-Value": [...], "Conclusion": [...] } """ Save the json answer in `/app/output/answer.json`. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
