Final Answer:
The exercise behavior of the student group, as described, indicates that approximately a quarter of them engaged in exercise for less than ten minutes per week, with varying levels reported by the rest.
Step-by-step explanation:
The passage describes the exercise habits of a student group, highlighting the duration and frequency of their physical activity. The key information reveals that around 25% of the students exercised for less than ten minutes per week. This suggests a significant portion of the group has minimal physical activity.
The mention of "weaker" exercise reported by some and "more than ten minutes" reported by another quarter indicates a diversity in exercise patterns within the remaining three-quarters of the group. It implies that a substantial portion of the students might have a moderate level of physical activity, falling within the range of ten minutes or more per week. The varied responses capture the heterogeneous nature of the group's exercise behavior, reflecting a spectrum from minimal to potentially more robust physical activity.
Overall, the data suggests a need for further investigation into the factors influencing the exercise habits of the student population and potential interventions to promote healthier lifestyles.
