Question Analysis
This question involves calculating the total number of students in a histogram whose weekly video game hours are 10 or fewer.
The main focus is on identifying intervals that fit the condition ("10 or fewer") and summing their frequencies.

Key Concept Explanation
Frequencies of Intervals Within a Threshold: For conditions like "10 or fewer," we include all intervals where the upper bound is less than or equal to 10. This ensures we count only data points that do not exceed the threshold.

Step-by-Step Solution
Identify intervals with 10 or fewer hours:
The interval 1–5 has an upper bound of 5 (≤10).
The interval 6–10 has an upper bound ...
