children (ages Do popular cartoon characters on food packages influence children's food choices? A study asked 40 young 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% confidence interval, and test Ho: p = 0.5 versus Ha: p > 0.5.

Carry your intermediate computations to at least four decimal places, and round your answer to at least two decimal places.
A group of 100 BSSE girls from Riphah were selected to participate in a survey conducted by HEC to assess the satisfaction of students with online studies provided by the university. 48 % of the girls were high scorers while the rest were average scorers. 51 girls showed a lack of satisfaction with the studies including only 9 high scorers. Construct a 2 way cross tabulation and answer the following questions a. If a randomly selected student is an average score what is the probability that she would be satisfied with the studies b. What is the probability that a randomly picked student is a high scorer not satisfied with the studies c. What is the probability that a randomly picked students who is satisfied with the studies is a high-scorer girl

Participants in an experiment are asked to flip a fair coin and report the outcome. If they report H, they receive $10. If they report T, they receive $O. The experimenter observes that 70% of 1000 reports are H. How does this experiment provide evidence against or in favour of lying aversion? Please answer in at most three sentences.
