(a) A botanist at a nursery wants to inspect the health of the plants at the nursery. Which of the following best describes a convenience sample of plants? The botanist forms groups of 30 plants based on the heights of the plants. Then, he randomly chooses 3 groups and selects all of the plants in these groups. All of the plants that are in one particular room at the nursery are easily accessible. So, the botanist selects the 90 plants in this particular room. The botanist takes a list of the plants and selects every 5" plant until 90 plants are selected. |(b) The organizers of a conference want to survey attendees about the registration fee. Which of the following best describes a random sample of attendees? The organizers select the first 56 attendees who register for the conference because these attendees are easily accessible. The organizers form 7 groups of attendees based on the attendees' employment statuses. Then, the organizers select 8 attendees at random from each group. The organizers assign each attendee a different number. Using a random number table, the organizers draw 56 of those numbers at random. Then, the organizers select the attendees assigned to the drawn numbers. Every set of 56 attendees is equally likely to be drawn using the random number table. (c) Counselors at a college want to poll students about how much time the students spend studying. Which of the following best describes a systematic sample of students? The counselors take a list of the students and select every 3" student until 72 students are selected. The counselors form 6 groups of students based on the numbers of dasses the students are taking. Then, the counselors select 12 students at random from each group. The counselors use a computer program to draw 72 students at random and select these students. Every set of 72 students is equally likely to be drawn by the computer program. v 3rd
