21.14 Computer crime. Adults are spending more and more time on the Internet, and the number experiencing computer- or Internet-based crime is rising. A 2010 Gallup Poll of 1025 adults, aged 18 and over, found that 113 of those in the sample said that they or a member of their household were victims of computer or Internet crime on their home computer in the past year. Although the samples in national polls are not SRSs, they are similar enough that our method gives approximately correct confidence intervals.
