Explanation:

5. Dividing by population by voting precinct, and sampling everyone in the precincts selected is a cluster method as here first the division is made and then the division is elected and all the items in that division are sampled `.`

- Pulling 50 names from a hat = Simple random

- Asking your 20 closest friends = Convenience

- Separating all students by grade level, and selecting 10 students from each grade= Stratified

- Call every 15th phone number on every 5th page of the phone book = systematic

- Dividing by population by voting precinct, and sampling everyone in the precincts selected = Cluster

Final Answer

- Pulling 50 names from a hat = Simple random

- Asking your 20 closest friends = Convenience

- Separating all students by grade level, and selecting 10 students from each grade= Stratified

- Call every 15th phone number on every 5th page of the phone book = systematic

- Dividing by population by voting precinct, and sampling everyone in the precincts selected = Cluster
