The correct response is:
No, because not all people who own a cell phone have the same probability of being selected.
This response is valid because the survey was conducted only on customers between the ages of 20 and 30, which means it does not represent the broader population of all cell phone owners. Therefore, the conclusion that people own a cell phone for messaging purposes might not be applicable to those outside of this age range.
