Is the proportion of wildfires caused by humans in the south lower than the proportion of wildfires caused
by humans in the west? 339 of the 543 randomly selected wildfires looked at in the south were caused by
humans while 383 of the 543 randomly selected wildfires looked at the west were caused by humans. What
can be concluded at the = 0.01 level of significance?

(please show your answer to 3 decimal places.)
(Please show your answer to 4 decimal places.)
Select an answer the null hypothesis.
O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude
that the proportion of the 543 wildfires that were caused by humans in the south is lower than
the proportion of the 543 wildfires that were caused by humans in the west.
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 lower
than the population proportion of wildfires caused by humans in the west.
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.
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 lower than the
population proportion of wildfires caused by humans in the west.
