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.
simple random sample
probability sample
experiment
random sample

Explanation:

In a simple random sample of size n, each possible sample of that size has an equal chance of being selected. A probability sample is a more general term that includes various sampling methods where each element has a known non - zero probability of selection, but not necessarily equal for all samples of a given size. An experiment is a procedure carried out to test a hypothesis. A random sample is a general term for a sample selected randomly, but it doesn't always imply equal probability for all samples of a given size like a simple random sample does.

Answer:

Simple random sample
