Pete Thames, the general manager of the Winona Wildcats, a minor league baseball team, is concerned about the declining level of attendance the team's games in the past two seasons. He is unsure whether the decline is due to a national decrease in the popularity of baseball or to factors that are specific to the Wildcats. Having worked in the marketing research department of the team's major league affiliate, the New Jersey Lights, Thames is prepared to conduct a study on the subject. However, because it is a small organization, limited financial resources are available for the project. Fortunately, the Wildcats have a large group of volunteers who can be used to implement the survey. The study's primary objective is to discover the reasons why Winona residents are not attending games. A list of 1,200 names, which includes all attenders for the past two seasons, is available as a mailing list.
a. What is the target population for this study?
b. What is the appropriate sampling frame for this study of the attitudes of both attenders and nonattenders?
c. Which kind of sample would provide the most efficient sampling?
