The registrar at a small liberal arts college computes description summaries for all members of the entering class on a regular basis. For example, the average high school grade-point average (GPA) for the entering students in the most recent year was 3.16. The Chemistry department is interested in helping all new students who wish to take a chemistry class identify the appropriate course for them, so it offers a placement exam. The department randomly selects a subset of 175 students who took this exam during the past decade, and finds that they had an average score of 71.05 on the exam. The population of interest to the Chemistry department in this study is:
◦
the 175 selected students who took this exam during the past decade.
◦
all entering students during the most recent year.
◦
all entering students during the past decade.
◦
all students who took the chemistry placement exam during the past decade.
