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 401 supported raising the minimum wage. In city 2, a poll of 1000 randomly selected voters found that 435 supported raising the minimum wage.

In city 2, a poll of 1000 randomly selected voters found that 435 supported raising the minimum wage.

What type of hypothesis test should be performed?

\[
\hat{p}_1 = \text{Ex: 0.123}
\]

\[
\hat{p}_2 = \text{Ex: 0.123}
\]

\[
\hat{p} = \text{Ex: 0.123}
\]

Test statistic = Ex: 0.12

\( p \)-value = Ex: 0.123

Does sufficient evidence exist to support the claim that the level of support differs between the two cities at the \( \alpha = 0.05 \) significance level?
