71. 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 political campaign manager wants to know if the sample results can be used
to conclude that the unemployment rate for 18- to 34-years-olds 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 a = .05, what is your conclusion?
c. Explain to the campaign manager what can be said about the observed level of sig-
nificance for the hypothesis testing results using the p-value.
