Do people have better vision in their dominant eye compared to their non-dominant eye? A group of researchers randomly assigned people to either the "dominant" group or the "non-dominant" group. Each subject underwent an eye test which measured the vision in their dominant or non-dominant eye, according to their group assignment, and was given a score from 1 to 100. For this hypothesis test, which would be the appropriate alternative hypothesis? (Let group 1 = "dominant" group, and group 2 = "non-dominant" group.) (Note that example above was a null hypothesis, but now you've being asked to provide an alternative hypothesis.) :

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). Does this data provide enough evidence to show that Alaska had a lower proportion of identity theft than 23%? Test at the 5% level.
