Answer 1

To find which sample had the greatest proportion of students with at least one pet, we need to calculate the proportion for each sample. The proportion can be calculated using the formula:

\[ \text{Proportion} = \frac{\text{Number of Students with at Least 1 Pet}}{\text{Total Students in the Class}} \]

Now, let's calculate the proportion for each sample:

1. Sample Number 1:
   \[ \text{Proportion} = \frac{11}{19} \approx 0.5789 \]

2. Sample Number 2:
   \[ \text{Proportion} = \frac{12}{22} \approx 0.5455 \]

3. Sample Number 3:
   \[ \text{Proportion} = \frac{11}{17} \approx 0.6471 \]

4. Sample Number 4:
   \[ \text{Proportion} = \frac{9}{18} = 0.5000 \]

Now, let's compare the proportions:

• Sample 1: 0.5789
• Sample 2: 0.5455
• Sample 3: 0.6471
• Sample 4: 0.5000

The greatest proportion of students with at least one pet is in Sample Number 3 (approximately 0.6471).

Final answer: Sample number 3
