Situations comparing two proportions are described. In each
case, determine whether the situation involves comparing
proportions for two groups or comparing two proportions from the
same group. State whether the methods of this section
apply to the difference in proportions.
Compare the proportion of students who use a Windows-based PC to
the proportion who use a
Mac. Do the methods of this section apply to the difference in
proportions?

4. Comparing two population proportions (independent samples)
4. Comparing two population proportions (independent samples) Most major survey research organizations do not include wireless telephone numbers when conducting random-digit-dial telephone surveys. If there are differences between persons with and without landline phones, using a random-digit-dial telephone survey may introduce bias into the survey results. Data on a broad range of health topics are collected through personal household interviews of a representative sample of the U.S. civilian noninstitutionalized population in the National Health Interview Survey (NHIS) respondents are also asked about...

The popularity of computer, video, online, and virtual reality games has raised concerns about their ability to negatively affect youth, although the existing literature has been inconsistent. A recent survey of 14- to 18-year-olds in Connecticut high schools compared, among other things, aggressive behavior as evidenced by getting into serious fights for girls who have and have not played video games. When comparing two proportions such as these, the data can be...
