The correct response is:

No, because not all people who own a cell phone have the same probability of being selected.

The conclusion is not valid because the survey was conducted only among customers aged 20 to 30. This group does not represent the entire population of cell phone users, as preferences and reasons for owning a cell phone can vary significantly across different age groups. Therefore, the sample may not adequately reflect the reasons for cell phone ownership among the broader population.
