To find the percentage of students who own a bird as a pet based on the two samples, we first need to determine the total number of students who own birds from both samples and then divide that by the total number of students surveyed.
From the data provided:
- Sample 1: 8 students own a bird.
- Sample 2: 12 students own a bird.
Now, we can calculate the total number of bird owners:
Total bird owners = Bird owners from Sample 1 + Bird owners from Sample 2
Total bird owners = 8 + 12 = 20 students
Next, we find the total number of students surveyed across both samples:
Total students = Sample 1 total + Sample 2 total
Total students = 100 + 100 = 200 students
Now, we can calculate the percentage of students who own a bird:
Percentage of bird owners = (Total bird owners / Total students) × 100
Percentage of bird owners = (20 / 200) × 100 = 10%
Therefore, based on the two samples, 10% of students own a bird as a pet.
