Explanation:

• Question #3: Stratified sampling involves dividing the population into subgroups (counties in this case) and then randomly sampling from each subgroup. Here, Georgia's counties are the strata, and 10 people are randomly chosen from each county.
• Question #4: Cluster sampling divides the population into clusters (schools in this case). A sample of clusters (schools) is selected, and then all individuals within the selected clusters (all students from the selected schools) are included in the sample.

• Question #3: Stratified Sampling
• Question #4: Cluster Sampling
