Answer 2

Answer:

The correct choices are:

A. At random

D. Represent the population

Explanation:

• Random sampling ensures that every member of the population or group has an equal chance of representation.
• Random sampling eliminates the possibility of response or sample bias which gives a universal sample that uniformly represents all members of the population.
• A good sample should represent the entire population. This can be achieved by through random sampling.
• Convenience and volunteer based samples both have an increased risk of response bias. These samples will only represent selected individuals instead of the entire population.
