On the first page of new york times article in the pre-lab, the researchers claimed that “for every hour of television watched after age 25 it shortens the viewer’s life expectancy by 21.8 minutes”. consider the arguments of the students below who are evaluating the strength of the claim based on what they believe to be limitations of the study design: student 1: i am not sure i believe the claim. the study design involved surveys of real people and asked about general health, disease status, exercise, smoking, diet, and number of hours of tv watched each week. this data should have been discussed as a limitation of the study because people are not good judges about these types of things. student 2: i am not sure i believe the claim. i agree with student 1, but we should also question how the study participants were recruited. maybe the people who were surveyed do not represent the broader population. this should have been discussed by the authors as another limitation of the study. student 3: the claim is believable. the sample size used in the study is 12,000 adults. that is large enough to minimize any of the limitations of the study suggested by the other two students and therefore did not need to be discussed by the authors. which student provides the best argument for whether or not the claim should be questioned
