  • Story:

    Is it true that students
    tend to gain weight during their first year in college? Cornell Professor of Nutrition David Levitsky recruited students from two large sections
    of an introductory health course. Although they were
    volunteers, they appeared to match the rest of the freshman
    class in terms of demographic variables such as sex
    and ethnicity. The students were weighed during the first
    week of the semester, then again 12 weeks later. Based
    on Professor Levitsky’s data, estimate the mean weight
    gain in first-semester freshmen and comment on the
    “freshman 15.” (Weights are in pounds.)
