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. the population is the customers in the computer database. the sample is biased because the customers surveyed are more likely to value the service.

Explanation:

The population here is the customers in the computer database (since the company is looking at its own customer database for the survey group). The sample is biased because the 600 most loyal customers are surveyed. Loyal customers are more likely to have a positive view of the service, so the sample doesn't represent all customers (e.g., less loyal or non - loyal customers are excluded), leading to a biased sample (it over - represents the positive opinion group).

Answer:

• Population: the customers in the computer database
• Sample nature: biased
• Reason for biased sample: the customers surveyed are more likely to value the service (as they are the most loyal customers, so they are not a representative sample of all customers, including those who may not be as satisfied)
