A local company rents a large number of apartments to collegestudents throughout the school year. Suppose the company wants tostudy the differences based on one's academic year (i.e., freshman,sophomore, junior, and senior years). An intern says, "We couldcollect either a stratified sample or a quota sample, but (of thetwo options) a stratified sample would be better, if that'spossible.") Do you agree with this intern's point of view? Explainwhy or why not.

Many companies have employee wellness programs that encouragetheir employees to be active and have healthy behaviors. SoutheastMissouri State University has a "fitness tracking program" whereemployees wear smart watches and are rewarded for taking at least10,000 steps a day. Typically, when analyzing these types ofprograms, researchers are most interested in understanding the"extreme" users, i.e. (1) those who take a lot of steps and (2)those who barely move during the day. Suppose the researcherswanted to complete two separate multivariate analyses. One woulduse a sample of heavy movers and the other would be analyzed usinga sample of the least mobile employees. Which type of samplingmethod might be best in this study? Explain your rationale.

Suppose Toyota wants to study how many TV viewers recall the TVcommercials for its newest Toyota Prius model. Someone on themarketing team claims that "a sample of 800 viewers is alwaysbetter than a sample of 400 viewers. Period." Do you agree ordisagree with this statement? Explain your reasoning.
