A study asked 40 youngfour to six) to taste Graham Crackers presented in a package either with or without a popular cartoon character. When askedto 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 alonewould explain?STATE: There are two questions: What proportion p of young children prefer Graham Crackers packaged with popularcartoon 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.

Suppose p is the true proportion of young children, who prefer the food packages with popular…

1. You are going to ask people if they like ice cream, recording the answer Yes or No. You are going to ask until someone says Yes or you have asked four people. Write out the sample space for this random phenomenon.
When making an ice cream sundae, you have a choice of 33 types of ice cream flavors: chocolate (C), vanilla (V), or Moose Tracks (M); a choice of 22 types of sauces: hot fudge (H) or butterscotch (B); and a choice of 22 types of toppings: whipped cream (W) or fruit (F). If you are choosing only one of each, list the sample space in regard to the sundaes (combinations of ice cream flavors, sauces, and toppings) you could pick from.

Students at a large university have four places to get lunch: the cafeteria, the hut, the taco wagon, or the pizza place. An article in the school newsletter states that 70% of students prefer to get lunch in the cafeteria and the other three options are preferred equally. To investigate this claim, a random sample of 150 students is selected. Are the conditions for inference met?
A report describes results of a survey of nearly 2000 college faculty. The report indicates the following. • 30.3% reported that they use Twitter and 69.7% said that they did not use Twitter. • Of those who use Twitter, 39.1% said they sometimes use Twitter to communicate with students. Of those who use Twitter, 27.5% said that they sometimes use Twitter as a learning tool in the classroom. Consider the chance experiment that selects one of the study participants at random and define the following events. T = event that selected faculty member uses Twitter C = event that selected faculty member sometimes uses Twitter to communicate with students L = event that selected faculty member sometimes uses Twitter as a learning tool in the classroom
