Expert Solution
Step 1
a)
When individuals are selected at a regular interval from sampling frame, then this type of sampling is called systematic sampling. In given scenario teacher asks every sixth student who walks into the classroom to present the homework problems to the class. Hence systematic sampling method is used in this example.
b)
When population is divided into sub-groups depending upon the similar characteristics and then random sample is chosen from each sub-group, this type of sampling is called stratified sampling. In given example teacher randomly chooses three students from each row to present the homework problems to the class. Hence stratified sampling method is used in this example.
