1 answer

The correct answer is:

A) No because not all people who own a cell phone give the same probability of being selected.

The survey only includes customers between the ages of 20 and 30, which may not be representative of the entire population of cell phone owners. Additionally, the conclusion about messaging purposes assumes that the responses from this specific age group can be generalized to all cell phone owners, which is not valid without a more diverse and representative sample.
