Given: 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 215 supported raising the minimum wage. In city 2, a poll of 1000 randomly selected voters found that 221 supported raising the minimum wage. a. What type of hypothesis test should be performed? (right-tailed z-test, right-tailed t-test, left-tailed z-test or two-tailed t-test) b. p^1= c. p^2= d. p^= e. Test statistic(z) = f. p-value = g. Does sufficient evidence exist to support the claim that the level of support differs between the two cities at the α=0.1 significance level? (yes or no)
