Based on the information provided, the conclusion that people own a cell phone for messaging purposes is not necessarily valid. The survey was only conducted among customers between the ages of 20 and 30, which may not be representative of the entire population of cell phone owners. Additionally, the survey may not have included a wide enough range of reasons for owning a cell phone, leading to biased results. To draw a more accurate conclusion, the survey should be conducted among a more diverse group of participants and include a broader range of potential reasons for owning a cell phone.
