What percentage of pick-up truck drivers want their next vehicle purchase to be another pick-up truck?

Should the speed limit be decreased on the highway connecting two large cities?

How many pedestrians would use a walkway built over a busy road?

Step-by-step explanation:

We use samples when using an entire population is not feasible.

It is not reasonable to ask every pick-up truck driver what they want their next purchase to be; there are too many owners of pick-up trucks.  This means we should use a sample.

Many people drive a highway that connects two large cities.  It is not reasonable to survey every person that drives it, so we should use a sample.

On a busy road, we may have many pedestrians; this means we should use a sample instead of the entire population.
