  1.      Which   of  these   would   be  a   sampling    technique   for a   well-designed   survey  of  students    in  a   high

    school?
    (A) Number each student on a list of all students’ names. Use a random number generator on a
    calculator to randomly select 50 different numbers. The corresponding students will be in the
    sample.
    (B) Put up posters in the hallways and on classroom doors instructing students to text their responses
    to a particular number. Those who respond will be in the sample.
    (C) Have student council members ask the students in their third-hour class. The students in those
    third-hour classes will be in the sample.
    (D) Put a flyer on each student’s locker with the survey questions on it. Those who return their
    responses to the office will be in the sample.
    (E) Put a flyer with the survey questions on it next to the line in the cafeteria. Students can fill them
    out and drop them in a box in the cafeteria. Those who return the surveys will be in the sample.
