Do popular cartoon characters on food packages inuence children's food choices? A study asked 40 young children (ages four to six) to taste Graham Crackers presented in a package either with or without a popular cartoon character. When asked to indicate which of the two options they would prefer to eat for a snack, 35 chose the version with a cartoon on the package. Is this evidence that young children prefer snacks packaged with popular cartoon images more than chance alone would explain? STATE: There are two questions: What proportion p of young children prefer Graham Crackers packaged with popular cartoon images? Is there evidence that p is more than 0.5 (what chance alone would predict)? PLAN: Give a 95% condence interval, and test Hozp = 0.5 versus Hazp > 0.5. Obtain the zstatistc. Give your answer to two decimal places. 2: Obtain the Pvalue. If the exact Pvalue is not provided in Table B, use the upper bound value. Give your answer to four decimal places
