The conclusion is not valid for the following reason:
No, because not all people who own a cell phone have the same probability of being selected.
The sample only includes customers between the ages of 20 and 30, which means it may not represent the entire population of cell phone users. Additionally, the survey responses may be biased due to the narrow age range. Thus, it cannot be concluded that people own cell phones primarily for messaging based solely on this survey.
