To find out what percentage of the total students reported a grade average above 80%, we should follow these steps:

1. Summarize the data provided in the table:
- Students with less than 4 hours of screen time:
- Grade average above 80: 7
- Grade average below 80: 8
- Students with 4 - 8 hours of screen time:
- Grade average above 80: 14
- Grade average below 80: 11
- Students with 8 - 12 hours of screen time:
- Grade average above 80: 10
- Grade average below 80: 14
- Students with more than 12 hours of screen time:
- Grade average above 80: 11
- Grade average below 80: 15

2. Calculate the total number of students surveyed:
- Total for less than 4 hours: 7 (above 80) + 8 (below 80) = 15
- Total for 4 - 8 hours: 14 (above 80) + 11 (below 80) = 25
- Total for 8 - 12 hours: 10 (above 80) + 14 (below 80) = 24
- Total for more than 12 hours: 11 (above 80) + 15 (below 80) = 26
- Total number of students = 15 + 25 + 24 + 26 = 90

3. Calculate the total number of students with a grade average above 80:
- Total for less than 4 hours: 7
- Total for 4 - 8 hours: 14
- Total for 8 - 12 hours: 10
- Total for more than 12 hours: 11
- Total students with grade average above 80 = 7 + 14 + 10 + 11 = 42

4. Calculate the percentage of students with a grade average above 80:
- Using the formula: (Total students with grade average above 80 / Total number of students) 100
- Percentage = (42 / 90) 100 ≈ 46.67%

Thus, approximately 46.67% of the total students reported a grade average above 80.
