Answer
# Brief Explanations:
- Sample 1: Randomly selected from all phone - numbers, likely to cover a diverse range of adults in New Zealand, so it's representative.
- Sample 2: Only those who read the newspaper and respond are included. People who don't read that newspaper or don't respond are excluded, so it's not representative.
- Sample 3: Only licensed car - owners are considered. Non - car owners are excluded, so it's not representative.
- Sample 4: Only people visiting a particular Auckland grocery store are included. People from other areas and those who don't visit that store are excluded, so it's not representative.
# Answer:
Sample 1 is most likely to be a representative sample.
Sample 2 is not likely to be representative because it only includes those who read the newspaper and respond.
Sample 3 is not likely to be representative because it only includes licensed car - owners.
Sample 4 is not likely to be representative because it only includes people visiting a particular Auckland grocery store.
