A recent study explored the relationship between work-life balance and employee productivity across various industries. Researchers surveyed employees from tech, education, and healthcare sectors, finding that:

1. In the tech industry, employees who reported a balanced work-life experienced a 30% increase in productivity compared to those struggling with balance.

2. In education, teachers who maintained a healthy work-life balance reported feeling more engaged and motivated in their teaching duties, leading to improvements in student outcomes.

3. However, in the healthcare sector, the same correlation was weak, with high productivity levels observed in employees regardless of their claimed work-life balance.

Based on this study, which of the following conclusions can be most strongly supported?
