To determine which statement is true using relative frequencies, we should analyze the data in the table based on the preferences for hip-hop and pop among 10th and 11th graders.
-
If you like hip-hop, you are almost equally likely to be from 10th or 11th grade.
- Total hip-hop fans: 210 (112 from 10th grade and 98 from 11th grade)
- Proportion from 10th grade: 112 / 210 ≈ 0.533 (53.3%)
- Proportion from 11th grade: 98 / 210 ≈ 0.467 (46.7%)
- This statement is true because the proportions are relatively close.
-
If you are a 10th grader, you are more likely to prefer pop.
- Total 10th graders: 165 (53 prefer pop)
- Proportion of 10th graders who prefer pop: 53 / 165 ≈ 0.32 (32%)
- Proportion of 10th graders who prefer hip-hop: 112 / 165 ≈ 0.68 (68%)
- This statement is false.
-
If you like pop, you are more likely to be a 10th grader.
- Total pop fans: 200 (53 from 10th grade and 147 from 11th grade)
- Proportion from 10th grade: 53 / 200 = 0.265 (26.5%)
- Proportion from 11th grade: 147 / 200 = 0.735 (73.5%)
- This statement is false.
-
If you are an 11th grader, you are more likely to prefer hip-hop.
- Total 11th graders: 245 (98 prefer hip-hop)
- Proportion of 11th graders who prefer hip-hop: 98 / 245 ≈ 0.4 (40%)
- Proportion of 11th graders who prefer pop: 147 / 245 ≈ 0.6 (60%)
- This statement is false.
The correct answer is: If you like hip-hop, you are almost equally likely to be from 10th or 11th grade.
