Question

A company uses a computer to identify their 600 most loyal customers from its database and then surveys those customers to find out how they like their service. Identify the population and determine whether the sample is random or biased.

Answer 1

The population would be the total number of customers found in the database.

The sample would be BIASED because the computer will be identifying the 600 most loyal customers from the database.

Since their survey would be about the service of the company, choosing the most loyal customers will ensure that they would have a positive feedback on the service of the company. Customers build loyalty to a business when it has good service and staff.
