To find the percentage of students who own a bird as a pet based on the two samples, you can follow these steps:

  1. Calculate the total number of students who own a bird from both samples.

    • From Sample 1: 8 students own a bird.
    • From Sample 2: 12 students own a bird.

    Total students who own a bird = 8 + 12 = 20.

  2. Calculate the total number of students from both samples.

    • Sample 1: 100 students
    • Sample 2: 100 students

    Total students = 100 + 100 = 200.

  3. Calculate the percentage of students who own a bird: \[ \text{Percentage} = \left( \frac{\text{Number of Students Who Own a Bird}}{\text{Total Number of Students}} \right) \times 100 \] \[ \text{Percentage} = \left( \frac{20}{200} \right) \times 100 = 10% \]

Thus, the percentage of students who own a bird as a pet is 10%.
