What is the relative frequency of 8th graders who prefer cats. Round percentage to nearest tenth
To find the relative frequency of 8th graders who prefer cats, we need to add up all the 8th graders and then divide the number who prefer cats by that total.
Total 8th graders = 22 (preference for cats) + 26 (preference for dogs) + 6 (no preference) = 54
Relative frequency of 8th graders who prefer cats = 22/54 = 0.4074
To convert this to a percentage, we multiply by 100:
0.4074 * 100 = 40.74%
Rounded to the nearest tenth, the relative frequency of 8th graders who prefer cats is 40.7%.
