Examine the data from a survey of 10th and 11th graders about which music genre they prefer. Using relative frequencies, which of the following is true? 10th Grade Hip Hop Pop 110 50 160 11th Grade 99 150 249 Total 209 200 Totals 409

Answer 1

To calculate the relative frequencies, we divide the frequency of each genre by the total number of students surveyed.

For 10th grade:
Hip Hop: 110/409 ≈ 0.269
Pop: 50/409 ≈ 0.122

For 11th grade:
Hip Hop: 99/409 ≈ 0.242
Pop: 150/409 ≈ 0.367

Based on the relative frequencies, it is true that a higher proportion of 11th graders prefer Pop music compared to 10th graders.
