A team of community members hopes to use land in a current empty lot for a dog park. To determine if the community generally approves of the use of the lot for a dog park, volunteers survey shoppers leaving a pet store located near the lot. The results show that 83% of the 112 people surveyed approve of the dog park plan. How might the survey results be biased in estimating community support for a dog park?

The team could overestimate community support because some shoppers may choose to not respond to the survey.
The survey should show little bias and estimate community support well because a random sample of shoppers was chosen.
The team could overestimate community support because those surveyed may be more likely to support a park than the overall community would.
The team could underestimate community support because those surveyed may be less likely to support a park than the overall community would.
