The percentage of students who own a bird as a pet can be calculated as follows:
Total number of students who own a bird in Sample 1 = 8
Total number of students who own a bird in Sample 2 = 12
Total number of students who own a bird in both samples = 8 + 12 = 20
Total number of students in both samples = 100 + 100 = 200
Percentage of students who own a bird as a pet = (20 / 200) x 100 = 10%
Therefore, 10% of the students in the two samples own a bird as a pet.
The data from two random samples of 100 students regarding what pet they own is given below.
