Television advertisers may mistakenly believe that most viewers understand most of the advertising that they see and hear. A recent research study asked 2300 viewers above age 13 to look at 30-second television advertising excerpts. Of these, 1914 of the viewers misunderstood all or part of the excerpt they saw. Find a 95% confidence interval for the proportion of all viewers (of which the sample is representative) who will misunderstand all or part of the television excerpts used in this study.
