The conclusion is not valid. The correct response is:
**No, because not all people who own a cell phone have the same probability of being selected.**
This is because the survey only sampled individuals between the ages of 20 and 30, which does not represent the entire population of cell phone owners. Therefore, the reasons for owning a cell phone may differ significantly in other age groups.
