Question

why is a sample used more often than a population? choose the correct answer below. a. all samples are representative of a population, so the population does not need to be used. b. inferences cannot be made when using the population. c. it is usually impossible to count the entire population. d. sample statistics are more accurate than the population parameter.

Explanation:

Populations can be extremely large. Counting every member is often unfeasible due to time, cost, and practical limitations. Samples are used to make inferences about the population. Not all samples are representative (A is wrong), inferences can be made with populations (B is wrong), and population parameters are more accurate than sample statistics when known (D is wrong).

Answer:

C. It is usually impossible to count the entire population.
