Exercise 8 Page 316

A population consists of all of the members of a group of interest. Since it might be unrealistic to consider every member of a population, a sample is sometimes selected to represent the population. A sample is a subset of the population. The sample can then be analyzed to draw conclusions about the entire population.

Let's think about our situation.

The ticket manager (...) awarded prizes by drawing four numbers corresponding to the ticket stub numbers of four fans in attendance.

The sample consists of only 4 people selected to win a prize. Here, the population consists of all spectators who purchased tickets to attend the game.
