Is the proportion of wildfires caused by humans in the south lower than the proportion of wildfires caused by humans in the west? 403 of the 519 randomly selected wildfires looked at in the south were caused by humans while 422 of the 511 randomly selected wildfires looked at the west were caused by humans. What can be concluded at the Q = 0.10 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 Select an answer Select an answer + H1: Select an answer Select an answer Select an answer c. The test statistic? = d. The p-value = e. The p-value is ? (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The results are statistically insignificant at a = 0.10, 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 = 0.10, 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. The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude that the proportion of the 519 wildfires that were caused by humans in the south is lower than the proportion of the 511 wildfires that were caused by humans in the west. The results are statistically insignificant at a = 0.10, 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.
