The data from two random samples of 100 students regarding what pet they own is given below.
Sample 1: dog 54, cat 38, bird 8, total 100
Sample 2: dog 39, cat 49, bird 12, total 100
Based on the two samples, what percentage of students own a bird as a pet?
(1 point)
The percentage of students who own a bird as a pet can be found by taking the number of students who own a bird and dividing it by the total number of students in both samples, and then multiplying by 100:
(Number of students who own a bird / Total number of students) * 100
In Sample 1, there are 8 students who own a bird out of a total of 100 students.
In Sample 2, there are 12 students who own a bird out of a total of 100 students.
Therefore, the total number of students who own a bird in both samples 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) * 100 = 10%.
So, based on the two samples, 10% of the students own a bird as a pet.
