Answer

Mr. Berkman asks all his third-period students about music preferences.
B
Each customer of a sandwich shop is interviewed about their customer satisfaction as they exit.
C
An online poll about voter opinion of political issues is posted on social media.
D
A student organization interviews students in a lunch line about cafeteria meals.
E
Fifteen percent of families in the county are randomly chosen to respond to a survey about emergency services.
F
The management employees of a company, which has locations throughout the country, are asked about job satisfaction.
Explanation
Convenience sampling uses people who are readily available to the person conducting the survey. Mr. Berkman’s third-period students, customers leaving the sandwich shop, and students in the lunch line are all easy to reach in those settings. The social-media poll relies on people choosing to respond, while the county families are randomly selected; asking the company’s management employees targets a specific group rather than a readily available sample of the company’s workers.
