Explanation:

In random sampling, each member of the population has an equal chance of being selected. Here, telephone numbers were randomly generated by a computer to select the 707 adults for the poll, which fits the definition of random sampling. Cluster sampling involves dividing the population into clusters and randomly selecting some of the clusters. Stratified sampling divides the population into strata and samples from each stratum. Systematic sampling selects every k - th member of the population. Convenience sampling selects individuals who are easily accessible.
