Astudy 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? random selection sample voluntary response census

Based on the given scenario above, I can say that the sampling method that was used in this study is random sampling. When we say random sampling, this is the type of sampling method wherein you get a smaller part of the population from the general ones. In this case, from 583, 27 candidates are being selected. Hope this helps.
