Is the proportion of wildfires caused by humans in the south different from the proportion of wildfires caused by humans in the west? 380 of the 550 randomly selected wildfires looked at in the south were caused by humans while 404 of the 572 randomly selected wildfires looked at the west were caused by humans. What can be concluded at the a = 0.01 level of significance?

Is the proportion of wildfires caused by humans in the south different from the proportion of wildfires
caused by humans in the west? 380 of the 550 randomly selected wildfires looked at in the south were
caused by humans while 404 of the 572 randomly selected wildfires looked at the west were caused by
humans. What can be concluded at the a = 0.01 level of significance?

the null hypothesis.
O The results are statistically insignificant at a = 0.01, so there is insufficient evidence to
conclude that the population proportion of wildfires caused by humans in the south is different
from the population proportion of wildfires caused by humans in the west.
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 different from 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 550 wildfires that were caused by humans in the south is different
from the proportion of the 572 wildfires that were caused by humans in the west.
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.
