1 two pop proportions
Is the proportion of wildfires caused by humans in the south higher than the proportion of wildfires caused by humans in the west? 369 of the 525 randomly selected wildfires looked at in the south were caused by humans while 339 of the 546 randomly selected wildfires looked at the west were caused by humans. What can be concluded at the o = 0.01 level of significance? 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: p1 p2 (please enter a decimal) H 1: p1 V p2 V (Please enter a decimal) c. The test statistic t v X = 2.834 x (please show your answer to 3 decimal places.) d. The p-value = 0.0023 | (Please show your answer to 4 decimal places.) e. The p-value is s v v o f. Based on this, we should reject the null hypothesis. g. Thus, the final conclusion is that ... The results are statistically significant at o = 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. hs The results are statistically insignificant at o = 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 proportion of the 525 wildfires that were caused by humans in the south is higher than the proportion of the 546 wildfires that were caused by humans in the west. 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
