Answer 1

To find the relative frequency of 7th graders who prefer dogs, we first need to calculate the total number of 7th graders and then determine the proportion of those who prefer dogs.

From the table:

• 7th Graders who prefer Dogs: 8
• 7th Graders who prefer Cats: 36
• 7th Graders with No Preference: 2

Now, let's find the total number of 7th graders:

Total 7th Graders = 7th Graders who prefer Cats + 7th Graders who prefer Dogs + 7th Graders with No Preference Total 7th Graders = 36 + 8 + 2 = 46

Next, we calculate the relative frequency of 7th graders who prefer dogs:

Relative Frequency = (Number of 7th Graders who prefer Dogs) / (Total Number of 7th Graders) Relative Frequency = 8 / 46

Now, we can convert this to a percentage:

Relative Frequency Percentage = (8 / 46) * 100 ≈ 17.39%

Rounding to the nearest tenth, we get approximately 17.4%.

Thus, the correct answer is:

17.4%
