As part of a lesson in survey design, Janette asks her study team of four students the following question: *“Given the association between movie violence and crime, what kind of movie would you rather watch: romantic comedy or action?”* All four indicate they would rather watch a romantic comedy. She states in her conclusion, *“Obviously romantic comedies are the best.”* Homework Help ✎

If the population of movie goers is actually equally split between those who prefer romantic comedies versus action movies, what is the chance of finding a group of four who unanimously prefer one genre over the other? Is it plausible?

Draw a tree diagram.

Note: This is similar to flippingcoins because each person only has two choices. Write a few sentences commenting on the validity of Janette’s methods and her conclusion.

How was the question introduced?

Also, how many choices were students given?
