Question

Which of the following is/are true of a simple random sample (often referred to as an SRS) of size n from a population?

Taking an SRS is a good way to avoid sampling bias.

It has a high probability of producing a representative sample of the population.

It is the same as a haphazard sample.

All groups of size n in the population have the same chance of becoming the sample.

It can be obtained by taking a voluntary response sample of size n from the population.

Each member of the population has an equal chance of being selected.
