To find the percentage of students who own a bird as a pet from the two samples, we add the number of students who own a bird from each sample and divide by the total number of students in both samples.
Number of students who own a bird from sample 1 = 8
Number of students who own a bird from sample 2 = 12
Total number of students who own a bird = 8 (from Sample 1) + 12 (from Sample 2) = 20
Total number of students in both samples = 100 (from each sample) * 2 = 200
Percentage of students who own a bird as a pet = (20 / 200) * 100 = 10%
Therefore, based on the two samples, 10% of students own a bird as a pet.
The data from two random samples of 100 students regarding what pet they own is given below.
