Based on the provided data, we can calculate the relative frequencies for each category (hip-hop, pop, and totals):
- 10th grade hip-hop: 112/410 ≈ 0.273
- 10th grade pop: 53/410 ≈ 0.129
- 11th grade hip-hop: 98/410 ≈ 0.239
- 11th grade pop: 147/410 ≈ 0.359
Now we can compare the relative frequencies to determine which of the following is true:
1. 11th graders prefer hip-hop: 0.239
2. 10th graders prefer pop: 0.129
3. Pop is preferred by more 11th graders than 10th graders: 0.359
Based on the calculated relative frequencies, statement 3 is true.
hip-hop pop totals
10th grade 112 53 165
11th grade 98 147 245
total 210 200 410
