Is the proportion of wildfires caused by humans in the south lower than the proportion of wildfires caused by humans in the west? 358 of the 563 randomly selected wildfires looked at in the south were caused by humans while 358 of the 526 randomly selected wildfires looked at the west were caused by humans. What can be concluded at the a = 0.05 level of significance? %3D a. For this study, we should use z-test for the difference between two population proportions b. The null and alternative hypotheses would be: Ho: р1 p2 (please enter a decimal) H1: p1 p2 V (Please enter a decimal) c. The test statistic | z (please show your answer to 3 decimal places.) d. The p-value = (Please show your %3D answer to 4 decimal places.)
