The total number of students who own a bird as a pet is 8 + 12 = 20.
The total number of students in both samples is 100 + 100 = 200.
Therefore, the percentage of students who own a bird as a pet is:
(20/200) x 100 = 10%.
So, 10% of the students own a bird as a pet based on the two samples.
The data from two random samples of 100 students regarding what pet they own is given below.
Sample 1 : 54, 38, 8 = 100
Sample 2 : 39, 49, 12 = 100
Dog : 54, 39
Cat : 38, 49
Bird : 8, 12
Based on the two samples, what percentage of students own a bird as a pet?
