A political campaign is interested in whether a geographic difference existed in support for raising the minimum wage in a certain state. Polls were conducted in the two largest cities in the state about raising the minimum wage. In city 1, a poll of 800 randomly selected voters found that 269 supported raising the minimum wage. In city 2, a poll of 1000 randomly selected voters found that 303 supported raising the minimum wage. What type of hypothesis test should be performed? P1 = P2

What type of hypothesis test should be performed? [Dropdown menu]

\(\hat{p}_1 =\) [Textbox]

\(\hat{p}_2 =\) [Textbox]

\(\hat{p} =\) [Textbox]

Test statistic = [Textbox]

\(p\text{-value} =\) [Textbox]

Does sufficient evidence exist to support the claim that the level of support differs between the two cities at the \(\alpha = 0.01\) significance level? [Dropdown menu]

**Question:**

What type of hypothesis test should be performed?

- Right-tailed Z test
- Left-tailed Z test
- Left-tailed T test
- Two-tailed Z test

**Explanation (if applicable):**

This question provides options for selecting the appropriate hypothesis test based on the directionality and type of data distribution. The choices include right-tailed, left-tailed, and two-tailed tests using either the Z distribution (for larger sample sizes or known population variances) or the T distribution (typically for smaller sample sizes or unknown population variances).
