Hospital double line graph worksheet for K-5 students to practice data analysis and graphing skills.

Problem Analysis:

The task involves analyzing data about the number of patients admitted to a hospital over six days, categorized by gender (male and female). The data is provided in a table, and we need to answer specific questions based on this data. Additionally, we are required to draw a double line graph using the data.

#### Given Data:
| Day | Number of Patients |
|-----|---------------------|
| | Male | Female |
| Day 1 | 2 | 5 |
| Day 2 | 6 | 8 |
| Day 3 | 5 | 5 |
| Day 4 | 11 | 14 |
| Day 5 | 7 | 7 |
| Day 6 | 15 | 9 |

Solution to Each Question:

#### 1. How many more male than female patients were admitted on Day 5?
- On Day 5:
- Male patients: 7
- Female patients: 7
- Difference: \( 7 - 7 = 0 \)

Answer: 0

---

#### 2. How many more male than female patients were admitted on Day 2 and Day 6?
- Day 2:
- Male patients: 6
- Female patients: 8
- Difference: \( 6 - 8 = -2 \) (2 fewer males than females)

- Day 6:
- Male patients: 15
- Female patients: 9
- Difference: \( 15 - 9 = 6 \) (6 more males than females)

Answer: Day 2: -2; Day 6: 6

---

#### 3. On which day did the hospital admit the greatest number of patients?
- Total patients per day:
- Day 1: \( 2 + 5 = 7 \)
- Day 2: \( 6 + 8 = 14 \)
- Day 3: \( 5 + 5 = 10 \)
- Day 4: \( 11 + 14 = 25 \)
- Day 5: \( 7 + 7 = 14 \)
- Day 6: \( 15 + 9 = 24 \)

- The greatest total is 25, which occurred on Day 4.

Answer: Day 4

---

#### 4. What is the difference between the number of patients on Day 2 and Day 4?
- Total patients:
- Day 2: \( 6 + 8 = 14 \)
- Day 4: \( 11 + 14 = 25 \)
- Difference: \( 25 - 14 = 11 \)

Answer: 11

---

#### 5. Which days did the hospital admit an equal number of patients?
- Check each day for equality between male and female patients:
- Day 1: 2 (male) ≠ 5 (female)
- Day 2: 6 (male) ≠ 8 (female)
- Day 3: 5 (male) = 5 (female)
- Day 4: 11 (male) ≠ 14 (female)
- Day 5: 7 (male) = 7 (female)
- Day 6: 15 (male) ≠ 9 (female)

- Days with equal numbers of male and female patients: Day 3 and Day 5

Answer: Day 3 and Day 5

---

#### 6. How many days did the hospital have more male than female patients?
- Check each day:
- Day 1: 2 (male) < 5 (female)
- Day 2: 6 (male) < 8 (female)
- Day 3: 5 (male) = 5 (female)
- Day 4: 11 (male) < 14 (female)
- Day 5: 7 (male) = 7 (female)
- Day 6: 15 (male) > 9 (female)

- Days with more male patients: Day 6

Answer: 1 day

Drawing the Double Line Graph:

To draw the double line graph:
1. Label the x-axis as "Days" and the y-axis as "Number of Patients."
2. Use one line (e.g., solid) for male patients and another line (e.g., dashed) for female patients.
3. Plot the points for each day based on the given data:
- For males: (1, 2), (2, 6), (3, 5), (4, 11), (5, 7), (6, 15)
- For females: (1, 5), (2, 8), (3, 5), (4, 14), (5, 7), (6, 9)
4. Connect the points for each gender with lines.

Final Answers:

1. 0
2. Day 2: -2; Day 6: 6
3. Day 4
4. 11
5. Day 3 and Day 5
6. 1 day

Boxed Final Answer:
\[
\boxed{0, \text{Day 2: -2; Day 6: 6}, \text{Day 4}, 11, \text{Day 3 and Day 5}, 1}
\]
