Question

a study of a new medical procedure selected 27 candidates from a pool of 583 potential candidates. each of the potential candidates had an equal possibility of being chosen. which sampling method was used? (1 point) ○ sample ○ census ○ voluntary response ○ random selection

Explanation:

• "Sample" is a subset of the population, not a sampling method.
• "Census" involves studying the entire population, but here only 27 out of 583 are selected.
• "Voluntary response" relies on participants self - selecting, which is not the case here as each candidate has an equal chance.
• "Random selection" means each member of the population (potential candidates) has an equal probability of being chosen, which matches the description.

Answer:

D. random selection
