Answer

Answer:

  1. measuring the height of every fiftieth person on the school roster to determine the average height of the boys in the school
  2. taking a poll in the lunch room (where all students currently have to eat lunch) to determine the number of students who want to be able to leave campus during lunch

Brief Explanations:

The first option samples from the whole - school roster for boys' height, covering a wide range of the relevant population. The fifth option polls all students who eat lunch in the lunch room, which is a comprehensive way to reach the student population regarding lunch - time preferences. The second option only samples from a soccer team roster, not the whole population. The third option only samples people on Main Street at a specific time, not a representative cross - section of the population. The fourth option samples only parents in the school district, not all residents of the town.
