A community is considering raising funds to pay for improvements to the community swimming pool. To measure
Dennis_Churaev [7]

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.
