Answer

Explanation:

Step1: Identify relevant values

The number of seniors who have a dog is 2, and the total number of students is 50.

Step2: Calculate relative - frequency

The formula for relative frequency is $\text{Relative Frequency}=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\times100%$. So, $\text{Relative Frequency}=\frac{2}{50}\times100%$. $\frac{2}{50}\times100% = 4.00%$

Answer:

4.00
