Given:
A political campaign is interested in whether city 1 has less support for raising the minimum wage than city 2. 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 449 supported raising the minimum wage. In city 2, a poll of 1000 randomly selected voters found that 506 supported raising the minimum wage.
a. What type of hypothesis test should be performed? (right-tailed z-test, left-tailed t-test, two-tailed t-test, or left-tailed z-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 in city 1 is lower than that of city 2 at the α=0.1 significance level? (yes or no)
