Question

A study was conducted to see the number of pets who were

overweight. The results are in the following table:
​​​​​​​ Calculate the relative risk of being overweight for cat.

Answer 1

The relative risk for being overweight for cats can be calculated by dividing the probability of being overweight for cats by the probability of being overweight for other pets.

Step-by-step explanation:

The relative risk can be calculated by dividing the probability of being overweight for cats by the probability of being overweight for other pets.

Let's assume that the table provides the number of overweight and non-overweight pets for each category.

The relative risk for cats can be calculated as follows:

1. Calculate the probability of being overweight for cats by dividing the number of overweight cats by the total number of cats.
2. Calculate the probability of being overweight for other pets by dividing the number of overweight pets in other categories by the total number of pets in those categories.
3. Divide the probability of being overweight for cats by the probability of being overweight for other pets to calculate the relative risk.

For example, if there are 20 overweight cats out of 50 total cats and 30 overweight pets out of 100 total pets in other categories, the relative risk would be (20/50) / (30/100) = 0.67.
