Final answer:
To find the relative frequency of people owning a dog among those who live in a townhome, divide the number of townhome residents who own a dog by the total number of townhome residents.
Step-by-step explanation:
To answer the question, we need to calculate the relative frequency of people owning a dog among those who live in a townhome. Let's assume that there were a total of 100 people surveyed and 40 of them live in a townhome. Out of these 40 people, let's say 15 own a dog. To find the relative frequency, we divide the number of townhome residents who own a dog by the total number of townhome residents. So the relative frequency of owning a dog among people who live in a townhome is 15/40, which simplifies to 3/8 or 0.375.
