Hi there!

D. Statistics are knowable, but parameters are typically unknown.

Statistics are derived from a SAMPLE, whereas a parameter is found from the population.

A population could involve incredibly large numbers of individuals, which means that usually, a parameter is unknown because surveying ALL subjects within a population is unfeasible.

This is why samples are used to get statistics from, which provide a reasonable picture of the population if done correctly.
