Use the table to answer the question.
Preference 7th Graders 8th Graders
Prefers Cats 36 22
Prefers Dogs 8 26
No Preference 2 6
What is the relative frequency of students who prefer dogs who are 7th graders? Round the percentage to the nearest tenth.
To find the relative frequency of 7th graders who prefer dogs, we divide the number of 7th graders who prefer dogs by the total number of students:
Relative frequency = (Number of 7th graders who prefer dogs) / (Total number of students)
Relative frequency = 8 / (36 + 8 + 2)
Relative frequency = 8 / 46
Relative frequency = 0.1739
Converting this to a percentage, we multiply by 100:
Relative frequency = 0.1739 * 100
Relative frequency = 17.4%
Therefore, the relative frequency of 7th graders who prefer dogs is 17.4%.
