The conclusion is not valid. The correct answer is:
No, because not all people who own a cell phone have the same probability of being selected.
This emphasizes that the survey only targeted customers between the ages of 20 and 30, which limits the generalizability of the results to the broader population of all cell phone owners. Therefore, the findings cannot accurately represent the reasons for cell phone ownership across different age groups.
