To determine the accuracy of the statements based on the data from the table, we will calculate the relative frequencies for preferences of hip-hop and pop among 10th and 11th graders.

Total Students

  • Total 10th graders: 165
  • Total 11th graders: 245

Relative Frequencies for Preferences

  1. Pop Preference:

    • 10th graders preferring pop: 53

    • 11th graders preferring pop: 147

    • Relative frequency of pop preference:

      • For 10th graders: \( \frac{53}{165} \approx 0.321 \) (32.1%)
      • For 11th graders: \( \frac{147}{245} \approx 0.600 \) (60.0%)

    This indicates that if you like pop, you are more likely to be an 11th grader.

  2. Hip-Hop Preference:

    • 10th graders preferring hip-hop: 112

    • 11th graders preferring hip-hop: 98

    • Relative frequency of hip-hop preference:

      • For 10th graders: \( \frac{112}{165} \approx 0.678 \) (67.9%)
      • For 11th graders: \( \frac{98}{245} \approx 0.400 \) (40.0%)

    This indicates that if you like hip-hop, you are more likely to be a 10th grader.

  3. 10th Graders' Overall Preferences:

    • 10th graders prefer hip-hop more (112 out of 165) than pop (53 out of 165).
  4. 11th Graders' Overall Preferences:

    • 11th graders prefer pop more (147 out of 245) than hip-hop (98 out of 245).

Assessing the Statements:

  1. If you like pop, you are more likely to be a 10th grader.

    • False (more likely to be an 11th grader).
  2. If you like hip-hop, you are almost equally likely to be from 10th or 11th grade.

    • False (more likely to be 10th grader).
  3. If you are a 10th grader, you are more likely to prefer pop.

    • False (10th graders prefer hip-hop more).
  4. If you are an 11th grader, you are more likely to prefer hip-hop.

    • False (11th graders prefer pop more).

Conclusion:

None of the statements are true based on the relative frequencies from the data provided.
