The data from two samples of 100 students regarding what pet they own is given below.
Sample one: 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?
In sample one, 8 out of 100 students own a bird as a pet, which is 8%.
In sample two, 12 out of 100 students own a bird as a pet, which is 12%.
Therefore, combining the two samples, a total of 8% + 12% = 20% of students own a bird as a pet.
