Here's how to determine the class intervals from the given midpoints:
1. **Find the Class Width:**
The class width is the difference between consecutive midpoints. In this case:
22 - 17 = 5
27 - 22 = 5
The class width is consistent (5), which is what we expect.
2. **Determine the Boundaries:**
* **For the midpoint 17:**
* Subtract half the class width from the midpoint to get the lower boundary: 17 - (5/2) = 17 - 2.5 = 14.5
* Add half the class width to the midpoint to get the upper boundary: 17 + (5/2) = 17 + 2.5 = 19.5
* **For the midpoint 22:**
* Lower boundary: 22 - (5/2) = 22 - 2.5 = 19.5
* Upper boundary: 22 + (5/2) = 22 + 2.5 = 24.5
* **For the midpoint 27:**
* Lower boundary: 27 - (5/2) = 27 - 2.5 = 24.5
* Upper boundary: 27 + (5/2) = 27 + 2.5 = 29.5
3. **Write the Class Intervals:**
* 14.5 - 19.5
* 19.5 - 24.5
* 24.5 - 29.5
