A possible conclusion is that older people (in this case, people in their sixties) care more about their privacy than younger people. However, two important things need to be noted in this experiment:
1. This conclusion does not provide an explanation as to why this might be the case. We would need more information if we want to develop a theory that provides reasons for this situation to happen.
2. There might be other factors we have not study that might alter our conclusion. So it could only be a hypothesis until we have more information to rule other possibilities out.
