For a study on the health problems of drug users, a random sample of new york city high school students is drawn. a low level of health problems is found. jim argues that the findings are generalizable to new york city high school students because they were based on a random sample. meagan argues that the findings are not generalizable to high school students outside of new york city. how would you evaluate their positions?
a. neither claim can be correct since prescription drug use cannot be generalized to any population.
b. only jim is correct because he is referring to sample generalizability.
c. only meagan is correct because she is referring to cross-population generalizability.
d. both claims concerning sample and cross-population generalizability are correct.
