Samantha and Luis are attempting to determine the average number of library books that seventh-grade students check out at one t
ime. Samantha surveys every other seventh-grade student leaving the library. She samples a total of 40 of the 200 seventh graders. Luis samples 30 of the 200 seventh grade students at random in the school cafeteria. Whose sample is the most random?
Luis’ sample would be the most random, because not everyone in the cafeteria might check out books from the library, but since everyone Samantha surveyed was in the library already, most of the people she surveyed would be more consistent in their responses.
