Question

After the political ad campaign, pollsters check the mayor's negatives. They test the hypothesis that the ads produced no change against the alternative that the negatives are now below 65% and find a P-value of 0.483. Which conclusion is appropriate? Explain.

Solution

Since P-value is greater than 0.05 we can't reject the null hypothesis and should conclude that the ads produced no change.
