To find the relative frequency of students who prefer dogs and are 7th graders, you would use the formula:
Relative frequency = (Number of 7th graders who prefer dogs) / (Total number of students)
So in this case, the relative frequency would be:
Relative frequency = 8 / (36 + 8 + 2) = 8 / 46 = 0.1739
Converting this to a percentage, you would get 17.4%.
Therefore, the correct answer is:
17.4%
