**Histogram Analysis**

Data was collected for 327 randomly selected 10-minute intervals. For each ten-minute interval, the number of people entering the atrium of a large mall was recorded. The data is summarized in the histogram below.

**Histogram Details:**

- **Y-axis (Frequency):** Represents the frequency of intervals for the number of people entering.
- **X-axis (Number of People in 10 min):** The classes are marked as 60, 80, 100, 120, 140, 160.

**Bar Observations:**

1. **60 to <80:** Frequency is approximately 90.
2. **80 to <100:** Frequency is approximately 80.
3. **100 to <120:** Frequency is approximately 0.
4. **120 to <140:** Frequency is approximately 80.
5. **140 to <160:** Frequency is approximately 0.

**Question:**

What is the class width for this histogram (and corresponding GFD)? Note: Each class contains its lower class limit, but not its upper class limit.

**Class width = __**
