a) We want to know if business leaders in the community support the development of an “incubator” site at a vacant lot on the edge of town. We spend a day phoning local businesses in the phone book to ask whether they’d sign a petition.
b) We want to know if travelers at the local airport are satisfied with the food available there. We go to the airport on a busy day and interview every tenth person in line in the food court.
