(a) the organizers of a conference want to survey attendees about the registration fee. which of the following best describes a cluster sample of attendees? the organizers select the first 64 attendees who register for the conference because these attendees are easily accessible. 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. the organizers take a list of the attendees and select every 4th attendee until 64 attendees are selected.
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.
