Work Step by Step

Article: "Survey: More Americans get News from internet than from newspaper or radio." By Doug Gross, CNN Source: http://edition.cnn.com/2010/TECH/03/01/social.network.news/index.html The sample is the subset of the population which would be 2,259 Americans 18 and older out of all the Americans 18 and older. The inference is drawn from the Survey. "Almost all respondents, 92 percent, said they get their news from more than one platform." and "Only television news still outpaces the Internet, with 78 percent of respondents saying they watch local news and 73 percent saying they view a national network or cable news channel like CNN, Fox News or MSNBC."
