According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumer complaints ("Consumer fraud and," 2008). The overall concern is to determine if these data provide enough evidence to show that Alaska had a lower proportion of identity theft than 23%. For this problem, just state the random variable, the sample size, the population parameter, and the hypotheses.
