O Sample 1: The 537 adults in Alaska who respond to a survey published in a newspaper. O Sample 2: The first 537 people to visit a particular Anchorage grocery store one day O Sample 3: A set of 537 Alaskans with phone numbers randomly selected from a list of all phone numbers in Alaska. O Sample 4: A set of 537 Alaskans randomly selected from a list of all licensed car owners in Alaska.

Explanation / Answer

Sample 3: A set of 537 Alaskans with phone numbers randomly selected from a list of all phone numbers in Alaska.

This is because there are people who do not read newspaper, who must be getting the robocall. So they also should be included in the sample.

The people visiting a particular grocery store might be getting robocall from that store itself.

Again the licensed car owners may be getting more robocalls from the car companies.
