A poll was taken every month on how voters will vote on the next federal election. Here are the results of the poll: 1. Develop a 95% condence interval estimate for the dierence between the proportions of voters who will vote for the Liberals in the two populations. Show your calculations. 2. From the condence interval obtained in the previous problem, is there conclusive evidence that one of the proportions is signicantly dierent from the other?
