QUESTION:
The next four questions refer to the following information:
Robin Dunbar, a leading anthropologist at Oxford University who studies social networks, has suggested that there is a magical number for social networks that humans can manage: any grouping larger than 150 people becomes overwhelming.
With that in mind, a group of researchers at Facebook wanted to study more about how their average user manages their social networks. One study of 225 Facebook users found a mean of 338 friends. Facebook knows from prior studies of their users that the standard deviation is 44.
