Answer #1

A large company wants to administer a satisfaction survey to its current customers. Using their customer​ database, the company randomly selects 50 customers and asks them about their level of satisfaction with the company.

The type of sampling used in this problem is SIMPLE RANDOM SAMPLING.

Simple random sampling is the basic sampling technique where we select a group of subjects (a sample) for study from a larger group (a population). Each individual is chosen entirely by chance and each member of the population has an equal chance of being included in the sample. Every possible sample of a given size has the same chance of selection.
