The conclusion is not valid. The most appropriate answer is:
No, because not all people who own a cell phone have the same probability of being selected.
This is because the survey only included customers between the ages of 20 and 30, which limits the sample to a specific age group and does not take into account the reasons for cell phone ownership among all age groups. Therefore, the conclusion may not accurately represent the majority opinion of the entire population.
