Exercise 11 Page 316

a A sample is a subset of the population. The sample can then be analyzed to draw conclusions about all of the members of a group of interest.

Let's think about our situation.

Of the 652 passengers on a cruise shop, 30 attended the magic show on board.

Here, the sample consists of 30 passengers that attended the magic show.

b 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.

Let's think about our situation.

Of the 652 passengers on a cruise shop, 30 attended the magic show on board.

Here, the population consists of all 652 passengers on a cruise ship.
