1 answer

To analyze the survey data using relative frequencies, we first need to calculate the relative frequencies for the music preferences of both 10th and 11th graders.

Step 1: Calculate relative frequencies

For 10th Graders:

  • Total = 165
  • Hip-Hop: \( \frac{112}{165} \approx 0.6788 \)
  • Pop: \( \frac{53}{165} \approx 0.3212 \)

For 11th Graders:

  • Total = 245
  • Hip-Hop: \( \frac{98}{245} \approx 0.4 \)
  • Pop: \( \frac{147}{245} \approx 0.6 \)

Step 2: Compare preferences

  1. 11th graders are more likely to prefer hip-hop over pop music.

    • Relative frequency for hip-hop (11th Grade) is 0.4; for pop, it's 0.6.
    • This statement is false.
  2. If you like hip-hop, you are more likely to be an 11th grader.

    • Relative frequency for hip-hop (10th Grade) is approximately 0.6788; for 11th Grade, it's 0.4.
    • This statement is false.
  3. 10th graders are more likely to prefer hip-hop over pop music.

    • Relative frequency for hip-hop (10th Grade) is approximately 0.6788; for pop, it’s approximately 0.3212.
    • This statement is true.
  4. If you like pop music, you are more likely to be a 10th grader.

    • Relative frequency for pop (10th Grade) is approximately 0.3212; for 11th Grade, it’s approximately 0.6.
    • This statement is false.

Conclusion

The true statement is:

10th graders are more likely to prefer hip-hop over pop music.
