Before the Champions Trophy 2017 (sorry for reminding the pain of the finals), ABC predicted that 22% of the Champions Trophy Tournament audience would express an interest in seeing one of its forthcoming new television shows, including 'Fascinating Wins' and 'Super wickets'. ABC ran commercials for these TV shows during the Champions Trophy. The day after the Final Match, Intermediate Advertising Group sampled 1532 viewers who saw the commercials and found that 414 said that they would watch one of the ABC advertised shows
1. What is the point estimate of the proportion of the audience that said that they would watch the television shows after seeing the television commercials? Also calculate the interval estimate.
2. At α = .05, determine whether the intent to watch the ABC television shows significantly increased after seeing the television commercials. Formulate the appropriate hypotheses , compute the p-value and state your conclusion.
