Refer to Exercise 17, in which students were chosen from 464 colleges to participate in a survey.
a. Suppose that the 464 schools were randomly selected from all eligible colleges and universities and that all first-year students at those schools were surveyed. Explain what type of sample was used in the survey.
b. Why would the sampling method described in part (a) have been simpler to implement than a simple random sample of all first-year college students in the United States?
