question #2
a government poll to determine who uses the state parks in georgia surveyed 25 people chosen randomly from each of georgias
counties.
which type of sampling is used?
stratified
cluster
convenience
systematic

Explanation:

• Question #1: A convenience sample is one where the sample is chosen because it is easy to access. In this case, the television crew sampled students sitting in the student center at noon. This is a convenient location for the crew to sample from, rather than using a random selection method (like simple random, stratified random) or a volunteer - based method.
• Question #2: Stratified sampling involves dividing the population into subgroups (in this case, the counties of Georgia) and then taking a random sample from each subgroup. Here, 25 people are chosen randomly from each of Georgia's counties, which fits the definition of stratified sampling. Cluster sampling would involve taking entire groups (clusters) as samples. Convenience sampling is about easy access (not the case here as it's a structured sample from each county). Systematic sampling involves a fixed - interval selection method (not described here).

Answer:

Question #1: C. A convenience sample
Question #2: Stratified
