Most US adults have social ties with a large number of people, including friends, family, co-workers, and other acquaintances. It is nearly impossible for most people to reliably list all the people they know, but using a mathematical model, social analysts estimate that, on average, a US adult has social ties with 634 people. A survey of 1700 randomly selected US adults who are Internet users finds that the average number of social ties for the Internet users in the sample was 669 with a standard deviation of 732. Does the sample provide evidence that the average number of social ties for an Internet user is significantly different from 634, the hypothesized number for all US adults (α=0.10)? Show all details of the test.
