Samantha and Luis are attempting to determine the average number of library books that seventh-grade students check out at one time. 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?
O Luis because his sample is taken from the population of all seventh graders
O Luis because he samples fewer students
O Samantha because she samples more students
• Samantha because her sample is taken from the population of students who use the library
