Part A:
If 34 out of 50 respondents liked classic rock music, then the proportion of students who like classic rock can be calculated as: 34/50 = 0.68.

- The sample represents middle school students' favorite type of music: Yes
- The sample is not randomly selected: No
Therefore, the statements that apply are:
- The sample is randomly selected.
- The sample represents middle school students' favorite type of music.
