Questions: A internet site asks its members to call in their opinion regarding their reluctance to provide credit information online. What type of sampling is used? A. Stratified B. Systematic C. Convenience D. Cluster E. Simple random

The answer is C: Convenience.

Explanation for each option:

A. Stratified: This type of sampling involves dividing the population into distinct subgroups (strata) and then randomly sampling from each subgroup. In the given scenario, there is no indication that the population is divided into subgroups before sampling.

B. Systematic: Systematic sampling involves selecting every nth member of the population. There is no mention of a systematic approach to selecting members in the scenario.

C. Convenience: Convenience sampling involves selecting members of the population who are easily accessible or willing to participate. In this case, the internet site is asking its members to call in their opinions, which means they are relying on those who are readily available and willing to respond, making it a convenience sample.

D. Cluster: Cluster sampling involves dividing the population into clusters and then randomly selecting entire clusters. There is no indication that the population is divided into clusters in this scenario.

E. Simple random: Simple random sampling involves selecting members of the population entirely at random, with each member having an equal chance of being chosen. The scenario does not describe a random selection process.

Therefore, the correct answer is C: Convenience.
