The registrar of a college with a population of N=3,800 students is asked by the president to conduct a survey to measure satisfaction with the quality of life on campus. The accompanying table contains a breakdown of the 3,800 registered students, by gender and class designation. The registrar intends to take a probability sample of n=100 students and project the results from the sample to the entire population of full-time students. Complete parts (a) through (e).

a. If the frame available from the registrar's files is an alphabetical listing of the names of all N=3,800 registered students, select all types of samples you could take. Discuss.

A.

A simple random sample could be taken by randomly selecting

n=100 students, where each student has an equal probability of being selected.

B.

A stratified sample could be selected by dividing the population into separate subpopulations (or strata) defined by some common characteristic, such as gender, and then choosing a random sample from each strata.

C.

A cluster sample could be selected by dividing the population into separate clusters defined by some naturally occurring groups, such as geographic location, and then choosing a random sample from each cluster.

D.

A systematic sample could be selected dividing the

N=3,800 students into n=100 groups and then selecting the 17th student in each group.
