The manager of the customer service division of a major consumer electronics company is interested in determining whether the customers who have purchased a Blu-ray player made by the company over the past 12 months are satisfied with their products. What is the population of interest?

The population of interest is all customers who have purchased a Blu-ray player made by the company over the past 12 months.

Step-by-step explanation:

This is a common statistics practice, when we want to study something from a population, we find a sample of this population.

For example:

I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents, which would be the population of interest.

In this problem, we have that:

Sample of customers who have purchased a Blu-ray player made by the company over the past 12 months.

So the population of interest is all customers who have purchased a Blu-ray player made by the company over the past 12 months.
