Define the population for:?

Question

What would be the relevant population for the following:

1) A survey on the attitudes to smoking in the workplace
2) A survey on the attitudes to parking in residential areas near a new leisure centre.
3)Sampling public vehicles to check maintenance standards.
4) Sampling components manufactured using new equipment.

Answer 1

1) all people who work in a public setting

2) users of the leisure centre as well as neighborhood residents.

3) I'm not exactly sure what this is asking. It could possibly be all public vehicles and the maintenance records.

4) same issue with 3, maybe all components manufactured? Then you could compare the components manufactured with new equipment to components manufactured with the old equipment.

Answer 2

Population is the group of people you take the sample from.

1. People who work where people can smoke
2. People who live in the area
3. Whoever samples the vehicle
4. Whoever samples it using new equipment.

The sample is taken from those.
