Max organizes weekly concerts in the local park. He is interested in knowing what type of music people enjoy. Before one particular concert, he makes an announcement to the audience, and asks people to visit a web page and take a survey to vote on whether or not they liked the concert. 75 people take the survey, and 58% respond favorably.
