For a survey-inference question, identify the sample: the people actually asked. Then check whether a conclusion describes their group and the habit the survey measured. A percentage above supports saying “most.” The trap is extending the result to a broader group or claiming an effect the survey never tested.
Hints
- Hint 1
A sample is the people who were asked, not everyone at their school. Find the shared feature of the surveyed students. Which group do their answers speak about most directly?
- Hint 2
A majority means more than half. Compare the reported percentage with . Does it support saying “most” of the surveyed students reported the habit?
- Hint 3
A survey records what people say they do; it doesn't test whether a habit helps. Look for a conclusion that stays near the surveyed group and describes the habit they were asked about.
Step-by-step
Match the inference to the surveyed group
Step 1Identify who the survey reached
No Desmos needed. The question is about who was surveyed, not a calculation. The 150 students are the sample, the people actually asked. They were all sports-team members, so keep the inference close to the group surveyed; their answers don't automatically describe students outside those teams.
- Step 2
Interpret the percentage
A majority means more than half. Since , most of the students surveyed said they regularly drank energy drinks before practice or games. That percentage describes their answers, not a measured percentage for a larger group.
- Step 3
Choose the claim the survey supports
The survey asked about drinking energy drinks, not athletic performance, so it can't show whether the drinks help. The best-supported inference stays with the school's sports-team students: most students who participate on those teams drink energy drinks. Choice B.
