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, assume some state had 454 complaints of identity theft out of 1660 consumer complaints. Do these data provide enough evidence to show that the state had a higher proportion of identity theft than 23%? Test at the 10% level.
