Answer

Explanation:

Step1: Define cluster sampling

Cluster sampling divides the population into groups (clusters), then randomly selects some clusters and includes all members of the selected clusters in the sample.

Step2: Analyze each option

  • Option 1: Selecting the first 64 attendees is convenience sampling, not cluster sampling.
  • Option 2: Organizers form groups (clusters) based on registration - day, randomly choose 8 groups and select all attendees in those groups. This is cluster sampling.
  • Option 3: Selecting every 4th attendee is systematic sampling, not cluster sampling.

Answer:

The organizers form groups of 8 attendees based on the day the attendees registered. Then, the organizers randomly choose 8 groups and select all of the attendees in these groups.
