To find the relative frequency of students who prefer dogs who are 7th graders, we need to calculate the total number of 7th graders who prefer dogs and divide it by the total number of students surveyed.
Total number of 7th graders who prefer dogs: 8
Total number of 7th graders: 36 + 8 + 2 = 46
Relative frequency = (8/46) * 100% = 17.4%
Therefore, the correct answer is:
B) 17.4%
Use the table to answer the question.
Preference 7th Graders 8th Graders
Prefers Cats 36 22
