The conclusion is not valid. The appropriate response would be:
No, because not all people who own a cell phone have the same probability of being selected.
The survey only included customers between the ages of 20 and 30, which limits the findings to a specific age group and does not account for the diverse reasons people in other age groups might own cell phones. This means the results cannot be generalized to the entire population of cell phone owners.
