Determine the type of sampling. (ex. Simple Random Sampling, Purposive Sampling, and etc.) 1. To determine customer opinion of its boarding policy, Southwest Airlines randomly selects 60 flights during a certain week and surveys all passengers on the flights. 2. A member of Congress wishes to determine her constituency’s opinion regarding estate taxes. She divides her constituency into three income classes: low income households, middleincome households, and upper-income households. She then takes a simple random sample of households from each income class. 3. The presider of a guest lecture series at a university stands outside the auditorium before a lecture begins and hands every fifth person who arrives, beginning with the third, a speaker evaluation survey to be completed and returned at the end of the program.
