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. 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.
