Who Is More Trusting: Internet Users or Non-users? In a randomly selected sample of 2237 US adults, 1754 identified themselves as people who use the Internet regularly while the other 483 indicated that they do not use the Internet regularly. In additic to Internet use, participants were asked if they agree with the statement "most people can be trusted." The results show that 807 of the Internet users agree with this statement, while 130 of the non- users agree. The sample difference in proportions is as follows: Proportion of Trust among Internet Users - Proportion of Trust among Non-users = 807/1754 - 130/483 = 0.46 - 0.27 = 0.19 Suppose we wanted to make a confidence interval to account for the sampling variability. What is the uncertainty or Standard Error for this difference in proportions? (Round to two decimal places.) Anśwer:
