Negatives After the political ad campaign described in Exercise 11, part a, pollsters check the governor’s negatives.

b) There’s a 78% chance that the ads worked.

c) There’s a 22% chance that their poll is correct.

 d) There’s a 22% chance that natural sampling variation could produce poll results like these if there’s really no change in public opinion.
