What is sampling?

Sampling is a statistical technique that uses a small sample size to represent the entire population.

For instance,

  • Suppose that the proportion of New York state residents who are Seattle Seahawks fans, has to be estimated.
  • Let's say, 500 randomly selected New York state residents whether they are Seattle Seahawks fans, and expand this to the entire population of New York State residents.
  • Then,
  1. The sample is 500 residents.
  2. The population is all New York State Residents.

Now, according to the question here, a survey is passed to the customers, which will be called the sample.

Thus, the sample is the randomly selected customers and the correct option is (B).
