A recent study focused on the method of payment used by college students for their cell phone bills. Of the 1,220 students surveyed, 600 stated that their parents pay their cell phone bills. Use a 0.01 significance level to test the claim that the majority of college students' cell phone bills are paid by their parents. Identify the null and alternative hypotheses for this scenario. Test the claim that the majority of college students' cell phone bills are paid by their parents. Your response should include your decision and conclusion in the context of the scenario.

Last year, the proportion of tax filers that received a refund was 25%. An accountant believes this upcoming tax year will have a smaller proportion of tax refunds than the proportion from last year. Interested in studying this further, the accountant samples a few of their clients and determines the proportion that receive a refund for this upcoming tax year is 19%. As the accountant sets up a hypothesis test to determine if their belief about this upcoming tax year is correct, what is the accountant's claim?
The College of Graduate Studies at MNSU claims that more than 60% of undergraduate students at this university will go to graduate school.

A study sponsored by the American Savings Education Councilt included data from a survey of 1752 people age 19 to 39. One of the survey questions asked participants how satisfied they were with their current financial situation. Suppose you want to determine if the survey data provides convincing evidence that fewer than 10% of adults age 19 to 39 are very satisfied with their current financial situation. With p the proportion of adults age 19 to 39 who are very satisfied with their financial situation, what hypotheses should you test? %3D O Ho: p = 0.1 versus H: p + 0.1 Ho:p = = 0.1 versus H: p 0.9 O Ho: P = 0.1 versus H: p 0.1
According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in the U.S. in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumers ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a different proportion of identity theft than 23%? Test at 5% level.
