Answer 1

The most appropriate answer is:

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

The conclusion drawn by the company is not valid because the sample they surveyed is limited to customers aged 20 to 30, which does not represent the entire population of cell phone owners. Additionally, the random selection process may not have ensured that all demographics or reasons for owning a cell phone were adequately captured, leading to potential bias in the results.
