Question

which of the following corresponds to the case when every sample of size n has the same chance of being chosen? choose the correct answer below. experiment probability sample random sample simple random sample

Explanation:

The question is about identifying the sampling method where every sample of size \( n \) has an equal chance of being chosen. By definition, a simple random sample is one in which each possible sample of a given size \( n \) from the population has an equal probability of being selected. An "experiment" is a procedure to test something, a "probability sample" is a broader category (and "simple random sample" is a type of probability sample), and "random sample" is a less precise term compared to "simple random sample" for this specific definition. So the correct option is the one with "Simple random sample".

Answer:

Simple random sample
