Problem
Alpha level= 0.05. Researchers are interested in understanding how media matters for crime for fear of crime. In a survey of 400 people, they find that 21% of those who watch network news (N=120) report that they are "very concerned" about crime, compared with 64% of those who use social media (N=280) as their main source of news. How likely is it that network news watchers are concerned about crime at a lower proportion relative to social media users? We calculate our test statistic= -1.70
