Using sampling concepts, it is found that the correct option is:
This is a convenience sample and likely overestimates support for raising funds.
<h3>How are samples classified?</h3>
Samples may be classified as:
- Convenient: Drawn from a conveniently available pool.
- Random: All the options into a hat and drawn some of them.
- Systematic: Every kth element is taken.
- Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
- Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.
In this problem, people at the pool were surveyed, hence it is a convenience sampling.
Also, since it only involved pool users, the proportion may be overestimated, hence the correct option is:
This is a convenience sample and likely overestimates support for raising funds.
