Answer 1

To find the relative frequency of 8th graders who prefer cats, you would use the formula:

Relative frequency = Number of 8th graders who prefer cats / Total number of 8th graders

In this case, the number of 8th graders who prefer cats is 26 and the total number of 8th graders is 26 (8th graders who prefer cats) + 22 (8th graders who prefer dogs) + 6 (8th graders with no preference) = 54.

Relative frequency = 26 / 54 = 0.4815

To convert this to a percentage, multiply by 100:

0.4815 * 100 = 48.15%

Rounded to the nearest tenth, the relative frequency of 8th graders who prefer cats is 48.2%. So the correct answer is:

37.9%
