Save your output file(s) under `/app/output`. Identify the geographic region and fuel source with the highest median CO₂ emissions. Then, within each geographical region, perform ANOVA tests to determine if there are significant differences in CO₂ emissions among the different fuel sources. If the ANOVA results are significant, conduct pairwise t-tests between fuel sources within each region, applying the Bonferroni correction for multiple comparisons. Record your analysis results in the file named `anova_results.csv`, following the provided format. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
