Based on the data provided in the table, we can analyze the associations between the number of practice hours and competition levels.

  1. Music Competition Level 1–3: 23 students practice less than 5 hours a week, while 9 students practice more than 5 hours a week.
  2. Music Competition Level 4 or Higher: 10 students practice less than 5 hours a week, while 18 students practice more than 5 hours a week.

From the data:

  • A higher number of students practicing less than 5 hours are at competition levels 1–3 (23) compared to those at level 4 or higher (10).
  • A greater number of students practicing more than 5 hours are at level 4 or higher (18) compared to those at levels 1–3 (9).

From this analysis, we can conclude:

  • There is an association between competition level and the number of hours of practice. Specifically, students who practice more than 5 hours are indeed more likely to be in a higher competition level (4 or higher).

Therefore, the correct response based on the data is:

There is an association between the competition level and the number of hours of practice.
