Why is a sample used more often than a population? Choose the correct answer below.

a.) Inferences cannot be made when using the population.

b.) It is usually impossible to count the entire population.

c.) Sample statistics are more accurate than the population parameter.

d.) All samples are representative of a population, so the population does not need to be used.
