Then, within each geographical region, perform ANOVA tests to determine if there are significant differences in CO\u2082 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.
