Szklarska, Koziel, Bielicki, and Malina (2007) hypothesized that taller young men are more likely to move up the scale of educational attainment compared with shorter individuals from the same social background. They recruited 91,373 nineteen-year-old men to participate in the study. Do these participants most likely represent a sample or population? Explain.
a. The 91,373 nineteen-year-old-men likely represent a sample of all 19-year-old men in a much larger population.
b. The 91,373 nineteen-year-old-men likely represent a population of 19-year-old men.
c. The 91,373 nineteen-year-old-men likely represent a sample of men of all ages in a much larger population.
d. The 91,373 nineteen-year-old-men likely represent a population of men of all ages.
