Question
Is the proportion of wildfires caused by humans in the south higher than the proportion of wildfires caused
by humans in the west? 387 of the 556 randomly selected wildfires looked at in the south were caused by
humans while 358 of the 553 randomly selected wildfires looked at the west were caused by humans. What
can be concluded at the a = 0.01 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho: Select an answery Select an answerv Select an answerv (please enter a decimal)
Hj: Select an answer Select an answerv Select an answerv (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 ?v a
f. Based on this, we should Select an answerv the null hypothesis.
g. Thus, the final conclusion is that ...
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.
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 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 higher
than the population proportion of wildfires caused by humans in the west.
O The results are statištically significant at a = 0.01, so there is sufficient evidence to conclude
that the proportion of the 556 wildfires that were caused by humans in the south is higher than
the proportion of the 553 wildfires that were caused by humans in the west.
