Answer 1

Using sampling concepts, it is found that the representative samples are obtained as follows:

• The builders were chosen at random.

• The population included only builders who build in vicki’s town.

What is sampling?

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, a sample should include only builders from Vickie's hometown(as she is not looking from builders from other towns), and should be random, hence the correct options are given by:

• The builders were chosen at random.

• The population included only builders who build in vicki’s town.
