Is the proportion of wildfires caused by humans in the south lower than the proportion of wildfires caused by humans in the west? 347 of the 556 randomly selected wildfires looked at in the south were caused by humans while 341 of the 524 randomly selected wildfires looked at the west were caused by humans. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer v Select an answer V Select an answer v (please enter a decimal) H: Select an answer v Select an answer vSelect an answer v (Please enter a decimal) c. The test statistic ?v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the population proportion of wildfires caused by humans in the south is lower than the population proportion of wildfires caused by humans in the west. O The results are statistically insignificant at a = 0.05, 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. OThe results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the proportion of the 556 wildfires that were caused by humans in the south is lower than the proportion of the 524 wildfires that were caused by humans in the west. The results are statistically insignificant at a = 0.05, so there is insufficient evidence to conclude that the population proportion of wildfires caused by humans in the south is lower than the population proportion of wildfires caused by humans in the west.

Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that KO The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the population proportion of wildfires caused by humans in the south is lower than the population proportion of wildfires caused by humans in the west. O The results are statistically insignificant at a 0.05, 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. The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the proportion of the 556 wildfires that were caused by humans in the south is lower than the proportion of the 524 wildfires that were caused by humans in the west. CThe results are statistically insignificant at a = 0.05, so there is insufficient evidence to conclude that the population proportion of wildfires caused by humans in the south is lower than the population proportion of wildfires caused by humans in the west.
