Based on this, we should elect an answer the null hypothesis. g. Thus, the final conclusion is that O The results are statistically insignificant at a = 0.01, so there is statistically significant evidence to conclude that the population proportion of wildfires caused by humans in the south is equal to the population proportion of wildfires caused by humans in the west. %3D O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the population proportion of wildfires caused by humans in the south is higher than the population proportion of wildfires caused by humans in the west. O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the proportion of the 522 wildfires that were caused by humans in the south is higher than the proportion of the 563 wildfires that were caused by humans in the west.
