<h3>What is a survey?</h3>
A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.
We have an automotive service centre would like feedback on its customer service each customer receives a printed card after they pay for services with a short survey on which customer service is ranked on a scale from 1 to 5.
From the data given we can say, not everyone will choose to leave a review when leaving the store, and those who do will have been inconvenienced in some way and felt compelled to do so, while the rest of the customers left and went about their business.
Thus, the statement second "this is nonresponse bias because many customers may choose to not fill out the cards" would be the best choice.

Center (-6,7)
Radius = 9
