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:

	dog	cat	no pet	total
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 sophomore who has no pets?
? %
round your answer to the nearest hundred

Explanation:

Step1: Identify relevant values

The number of sophomores with no pets is 4, 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 $\frac{4}{50}$.

Step3: Convert to percentage

$\frac{4}{50}\times100\% = 8\%$

Answer:

8%
