To find the median and interquartile range (IQR) for both the butternut squash and acorn squash, we need to analyze the data provided from the line plots.

### Butternut Squash Weights:
- 0 lbs: 0
- 0.5 lbs: 1
- 1 lb: 3
- 1.5 lbs: 4
- 2 lbs: 4
- 2.5 lbs: 3
- 3 lbs: 0
- 3.5 lbs: 0
- 4 lbs: 0
- 4.5 lbs: 0
- 5 lbs: 0

**Data Points for Butternut Squash (weights in lbs):**
- 1 (3 times)
- 1.5 (4 times)
- 2 (4 times)
- 2.5 (3 times)

This gives us the following list of weights:
- 1, 1, 1, 1.5, 1.5, 1.5, 1.5, 2, 2, 2, 2, 2.5, 2.5, 2.5

**Step 1: Find the Median**
To find the median:
- The median is the middle number. For 15 values, the median is the 8th value.
- In our sorted data: 1, 1, 1, 1.5, 1.5, 1.5, 1.5, **2**, 2, 2, 2, 2.5, 2.5, 2.5

Median = 2 lbs

**Step 2: Find the IQR**
To find the IQR:
- The first quartile (Q1) is the median of the first half of the data:
- Lower half: 1, 1, 1, 1.5, 1.5, 1.5, 1.5 (7 values)
- Median of lower half (4th value) = 1.5

- The third quartile (Q3) is the median of the second half of the data:
- Upper half: 2, 2, 2, 2, 2.5, 2.5, 2.5 (7 values)
- Median of upper half (4th value) = 2

- Calculate IQR:
IQR = Q3 - Q1 = 2 - 1.5 = 0.5

### Acorn Squash Weights:
- 0 lbs: 0
- 0.5 lbs: 0
- 1 lb: 0
- 1.5 lbs: 0
- 2 lbs: 4
- 2.5 lbs: 3
- 3 lbs: 1
- 3.5 lbs: 2
- 4 lbs: 3
- 4.5 lbs: 2
- 5 lbs: 0

**Data Points for Acorn Squash (weights in lbs):**
- 2 (4 times)
- 2.5 (3 times)
- 3 (1 time)
- 3.5 (2 times)
- 4 (3 times)

This gives us the following list of weights:
- 2, 2, 2, 2, 2.5, 2.5, 2.5, 3, 3.5, 4, 4, 4

**Step 1: Find the Median**
To find the median:
- In our sorted data: 2, 2, 2, 2, 2.5, 2.5, 2.5, **3**, 3.5, 4, 4, 4

Median = 3 lbs

**Step 2: Find the IQR**
To find the IQR:
- The first quartile (Q1) is the median of the first half of the data:
- Lower half: 2, 2, 2, 2, 2.5, 2.5 (6 values)
- Median of lower half (average of 3rd and 4th value) = (2 + 2) / 2 = 2

- The third quartile (Q3) is the median of the second half of the data:
- Upper half: 2.5, 3, 3.5, 4, 4, 4 (6 values)
- Median of upper half (average of 3rd and 4th value) = (3.5 + 4) / 2 = 3.75

- Calculate IQR:
IQR = Q3 - Q1 = 3.75 - 2 = 1.75

### Summary Table:
| | Median | Interquartile Range |
|----------|--------|---------------------|
| Butternut| 2 | 0.5 |
| Acorn | 3 | 1.75 |

Thus, the completed table will look like:

**Butternut**
- Median: 2
- Interquartile range: 0.5

**Acorn**
- Median: 3
- Interquartile range: 1.75
