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 332 supported raising the minimum wage. In city 2, a poll of
1000 randomly selected voters found that 407 supported raising the minimum wage.
