The unemployment rate for 18-to 34-year-olds was reported to be 10.8% (The Cincinnati Enquirer, November 6, 2012). Assume that this report was based on a random sample of four hundred 18- to 34-year-olds.

a. A political campaign manager wants to know if the sample results can be used to conclude that the unemployment rate for individuals 18 to 34 years old is significantly higher than the unemployment rate for all adults. According to the Bureau of Labor Statistics the unemployment rate for all adults was 7.9%. Develop a hypothesis test that can be used to see if the conclusion that the unemployment rate is higher for 18- to 34-year-olds can be supported

b. Use the sample data collected for the 18-to 34-year-olds to compute the p-value for the hypothesis test in part (a). Using α = .05, what is your conclusion?

c. Explain to the campaign manager what can be said about the observed level of significance for the hypothesis testing results using the p-value.
