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 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 5 .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
the
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 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 5 .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
