A random sample of 500 adult residents of Maricopa County found that 361 were in favor of increasing the highway speed limit to 75 mph, while another sample of 400 adult residents of Pima County found that 283 were in favor of the increased speed limit. Do these data indicate that there is a difference in the support for in increasing the speed limit between the residents of the two counties? Use a -0.05. (a) Test the hypothesis Ho: P₁ = P2 versus H₁: P₁ P2. What is zo? Round your answer to two decimal places (e.g. 98.76). Zo = (b) Is it reasonable to conclude that there is a difference in the support for increasing the speed limit between the residents of the two counties?

![**Hypothesis Testing: Comparing Two Proportions**
A random sample of 500 adult residents of Maricopa County found that 361 were in favor of increasing the highway speed limit to 75 mph, while another sample of 400 adult residents of Pima County found that 283 were in favor of the increased speed limit. Do these data indicate that there is a difference in the support for increasing the speed limit between the residents of the two counties? Use a significance level (\(\alpha\)) of 0.05.
(a) **Test the Hypothesis**
- **Null Hypothesis (\(H_0\))**: \(p_1 = p_2\)
- **Alternative Hypothesis (\(H_1\))**: \(p_1 \neq p_2\)
What is the test statistic (\(z_0\))? Round your answer to two decimal places (e.g., 98.76).
\[ z_0 = \text{[Input field]} \]
(b) **Conclusion**
Is it reasonable to conclude that there is a difference in the support for increasing the speed limit between the residents of the two counties?
\[ \text{[Dropdown selection for yes or no]} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0fea1cc5-2b25-43ff-974f-07cd43569663%2F17101a23-1096-41e7-9c71-7451dd0d5787%2Fuhq56lo_processed.png&w=3840&q=75)
