A major home improvement store conducted its biggest brand recognition campaign in the company's history. A series of new television advertisements featuring well-known entertainers and sports figures were launched. A key metric for the success of television advertisements is the proportion of viewers who "like the ads a lot". A study of 1,189 adults who viewed the ads reported that 230 indicated that they "like the ads a lot." The percentage of a typical television advertisement receiving the "like the ads a lot" score is believed to be 22%. Company officials wanted to know if there is evidence that the success of the series of television advertisements is different than the typical ad (i.e. if there is evidence that the population proportion of "like the ads a lot" for the company's ads is different than 0.22) at a 0.01 level of significance.What will be the p-value for the test? NOTE: show 3 decimal places in your answer.

The lowest level of significance at which the null hypothesis can be rejected is

An ad agency has developed a TV ad for the introduction of a toothpaste. The objective of the ad is to create brand awareness. The effectiveness of the ad is measured by aided- and unaided-recall scores. 200 respondents who claimed to have watched the TV show in which the ad was aired the night before have been contacted by telephone in 20 cities. In order for the ad to be successful, the percentage of unaided calls must be above 18 percent, which is the category norm for a TV commercial for the product class. Suppose out of 200 respondents 46 of them were able to recall the commercial without any prompting (unaided recall). Based on the information contained in the data, can we conclude that the ad was successful?
