Of the Internet users, 1054 use a social networking site.- Find and interpret a 95% confidence interval for each of the following proportions: (a) Proportion of US adults who use the Internet regularly. (b) Proportion of US adult Internet users who use a social networking site. (c) Proportion of all US adults who use a social networking site. Use the confidence interval to estimate whether it is plausible that 50% of all US adults use a social networking site.
