In sample 1, 54 students own a dog out of a total of 100 students. Therefore, the percentage of students who own a dog as a pet in sample 1 is:
(54/100) * 100 = 54%
In sample 2, 39 students own a dog out of a total of 100 students. Therefore, the percentage of students who own a dog as a pet in sample 2 is:
(39/100) * 100 = 39%
Therefore, the overall percentage of students who own a dog as a pet in both samples is:
[(54+39)/(100+100)] * 100 = 93/200 * 100 = 46.5%
So, 46.5% of the students own a dog as a pet in the combined sample.
