Question
After the political ad campaign, pollsters check the governor's negatives. They test the hypothesis that the ads produced no change against the alternative that the negatives are now below 30% and find a p-value of 0.22. Which conclusion is appropriate? Explain. a) There is a 22% chance that the ads worked. b) There is a 78% chance that the ads worked. c) There is a 22% chance that the poll they conducted is correct. d) There is a 22%. chance that natural sampling variation could produce poll results like these (or more extreme) if there is really a change in public opinion. e) There is a 22% chance that natural sampling variation could produce poll results like these (or more extreme) if there's really no change in public opinion.Explanation / Answer
The option e is correct. Here P-value shows the probability of getting the sample results assuming that null hypothesis is true.
Since p-value is large so fail to reject the null hypothesis.
