![### Distribution of Black Cherry Tree Heights
The distribution of the heights in feet of black cherry trees is shown in the histogram below.
**Histogram Explanation:**
- **X-Axis (Height ft):** This axis represents the height of the black cherry trees in feet, with intervals marked as 40, 45, 50, 55, 60, 65, 70, 75.
- **Y-Axis (Frequency):** This axis shows the frequency, or the number of trees that fall within each height interval.
**Bars:**
1. The first bar (40 to 45 feet) has a frequency of 1.
2. The second bar (45 to 50 feet) has a frequency of 4.
3. The third bar (50 to 55 feet) has a frequency of 6.
4. The fourth bar (55 to 60 feet) has a frequency of 3.
5. The fifth bar (60 to 65 feet) has a frequency of 2.
6. The sixth bar (65 to 70 feet) has a frequency of 1.
7. The seventh bar (70 to 75 feet) has a frequency of 2.
