Samantha and Luis are attempting to determine how many library books each seventh grade student checks out at the same time. Sam
antha 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 mostrandom? Luis because his sample is taken from the population of all seventh graders
Luis because he samples fewer students
Samantha because she samples more students
Samantha because her sample is taken from the population of students who use the library
I would choose A. Samantha is testing the actual question "how many LIBRARY books are checked out by 7th graders at SAME time". She is still getting a result to the question, but an inaccurate reading as we do not know if ALL 7th graders are present in library and she is only doing a portion of 7th graders checking out books. However, Luis is going to cafe and some may never have gone to library or dislike reading tangible material. Basically both are bad surveyors, but Luis is definlately performing a more random approach.
