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, “*It is obvious 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 4 who unanimously prefer one genre over the other? Is it plausible?

Write a few sentences commenting on the validity of Janette’s methods and her conclusion.

Draw a tree diagram.

Note: This is similar to flipping 4 coins because each person only has two choices.

How was the question introduced?

Also, how many choices were students given?
