Suppose that the unemployment rate for 18- to 34-year-olds was reported to be 10.6%. 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.
