Question

a survey was conducted at a high school to study pet ownership in different grade levels. the data gathered is in the two - way table below: table data: dog, cat, no pet, total; freshman: 3, 3, 5, 11; sophomore: 5, 7, 4, 16; junior: 8, 1, 3, 12; senior: 2, 3, 6, 11; total: 18, 14, 18, 50 based on this table, what is the relative frequency that a student is a freshman who has a cat? ?% round your answer to the nearest hund

Explanation:

Step1: Identify relevant values

The number of fresh - men who have a cat is 3, and the total number of students is 50.

Step2: Calculate relative frequency

The formula for relative frequency is $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So the relative frequency is $\frac{3}{50}=0.06$.

Step3: Convert to percentage

To convert a decimal to a percentage, multiply by 100. So $0.06\times100 = 6\%$.

Answer:

6%
