Gun violence is a serious problem in the United States. In 2011, 478,400 violent crimes were committed with a firearm (Planty and Truman, 2013). While down dramatically since the 1990s, the rate of non-fatal firearm victimizations rose from 2008 to 2011. Firearms deaths from all causes (homicides, suicides, accidental, and undetermined) averaged over 31,000 annually in 2005-2011 (CDC WISQARS, 2013; Hoyert and Xu, 2012). Non-fatal gunshot injuries totaled 81,396 in 2012; a rise in the injury rate per 100,000 from 20.5 in 2002 to 25.9 in 2012 (CDC, 2013). (SourceLinks to an external site.) In 2012, the proportion of American households who own a gun in their homes is 32%. As a Statistician: You want to further investigate and decide to estimate the true population proportion of American households that own at least one firearm. You take a random sample of 1281 American households and asked respondents whether or not they keep a gun in their homes and 34.4% of respondents said that they have at least one firearm in their home. 2. Estimate the population proportion of American households who own at least one firearm with a 95% level of confidence. 3. A. [1 pt] State ^. B. [2 pts] Verify the conditions. C. [3 pts] Compute the Margin of Error (using the Standard Error and Critical Value) D. [2 pts] State the confidence interval E. [4 pts] State and interpret the conclusion
