Answer 1

The conclusion that people own a cell phone primarily for messaging purposes is not valid based solely on the survey conducted with customers between the ages of 20 and 30. Here's the reasoning behind this:

• The sample only includes individuals aged 20 to 30, which is a narrow age range. It does not represent the entire population of cell phone owners, as people outside that age range may have different reasons for owning a cell phone.
• The survey may not capture the diversity of reasons why people across all age groups own cell phones.

Consequently, the most appropriate response is:

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

This response highlights the issue with generalizing the conclusions drawn from a non-representative sample.
