A researcher wants to study and compare the attitudes of the private and public university within the PAC-10. He wants to select 200 students to interview and wants to use stratif sampling. Which of the following strategies will enable him to accomplish his goal?
A) Randomly select 100 students from a randomly selected public PAC-10 university outside California and 100 students from either USC or Stanford, since he is not interested in having all the students in the same state.
B) Select 100 students out the combined enrollments of USC and Standford, and 100 students out of the combined enrollments of the other eight universities, since he is not interested in cluster sampling.
C) Randomly select 100 students from UCLA and 100 from USC since they are in the same city.
D) Select 100 students out of a large lecture section (more than 200 ) at California and Stanford since the students are naturally collected there already.. y students

Stratified sampling involves dividing the population into subgroups (strata) and then taking a sample from each stratum. In this case, the strata are the private universities (USC and Stanford) and the public universities (the other eight). Option B correctly divides the population into these two strata and proposes sampling 100 students from each, aligning with the goal of comparing attitudes between private and public university students within the PAC-10.
