Question Analysis
This question involves identifying the tallest and shortest intervals in a histogram (by frequency) and finding the difference between their frequencies.
The main focus is on comparing frequencies across intervals and performing subtraction.

Key Concept Explanation
Tallest vs. Shortest Intervals: The "tallest interval" has the highest frequency, and the "shortest interval" has the lowest frequency. The difference is calculated as (highest frequency) - (lowest frequency).

Step-by-Step Solution
Identify the tallest interval: The 30–39 inches interval has a frequency of 12 (highest).
Identify the shortest interval: The 10–19 inches interval has ...
