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 no pets? round your answer to the nearest hund

Explanation:

Step1: Identify relevant values

The number of freshmen with no pets is 5, 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 $\frac{5}{50}$.

Step3: Convert to percentage

$\frac{5}{50}=0.1$, and $0.1\times100 = 10\%$.

Answer:

10%
