• One of the questions in the Pew Internet & American Life Project asked adults if they used the Internet at least occasionally (Pew website, October 23, 2012). The results shows that 454 out 478 adults aged 18-29 answered Yes; 741 out of 833 adults aged 30-49 answered Yes; 1058 out of 1644 adults aged 50 and over answered Yes.
  • Develop a point estimate of the proportion of adults aged 18-29 who use the internet.
  • Develop a point estimate of the proportion of adults aged 30-49 who use the internet.
  • Develop a point estimate of the proportion of adults aged 50 and over who use the internet.
  • Comment on any relationship between age and Internet use that seems apparent.
  • Suppose your target population of interest is that of all adults (18 years of age and over). Develop an estimate of the proportion of that population who use the Internet.
