Answer 1

The correct response is:

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

The survey only sampled customers between the ages of 20 and 30, which may not accurately represent the entire population of cell phone owners. This limited age range can introduce bias and lead to invalid conclusions about why people own cell phones in general. A more representative sample is needed to make a valid conclusion about the reasons for cell phone ownership among the broader population.
