The Bureau of Labor Statistics reports a 6.0% unemployment rate for Americans whose maximum attained level of education is a high school diploma (Bureau of Labor Statistics website, December 5, 2015). Is the unemployment rate significantly different for Americans who have earned their bachelor's degrees? Suppose we have a random sample of 500 Americans whose maximum attained level of education is a bachelor's degree and found 18 who are unemployed. Use these sample results to conduct a hypothesis test to determine whether the unemployment rate for Americans whose maximum attained level of education is a bachelor's degree differs significantly from the unemployment rate for Americans whose maximum attained level of education is a high school diploma.
a. State the appropriate hypotheses for your significance test.
b. U se the sample results to compute the test statistic and the p-value.
c. Using α = .10, what is your conclusion?
