Suppose, to select a sample from a population of 3000 persons, the following procedure is followed. The names of the people are written on identical, square pieces of thin cardboard measuring one inch on a side, and these pieces of cardboard are then tumbled in a clothes dryer (with the heat shut off). After 30 minutes, a blindfolded person reaches in and withdraws a selected number of names. What can be said about this sample

One can conclude that this sample is obtained through a simple random sampling technique.

Step-by-step explanation:

With a simple random sampling, each population participant has an equal chance of being selected.  This sampling method is the best sampling technique when compared with other random sampling methods like the Stratified Random Sampling and Double-stage Random Sampling.  The reason is that it gives equal chance to every sample to be chosen by eliminating sample bias.
