A large nationwide poll recently showed an unemployment rate of 9% in the US. The mayor of a local town wonders if this national result holds true for her town, so she plans on taking a sample of her residents to see if the unemployment rate is significantly different than 9% in her town. What would be a Type I error in the contest of this problem? a. Claiming that the unemployment rate is 9% when it actually is different from 9%.
b. Claiming that the unemployment rate is different from 9% when it is actually 9%.
c. Claiming that there is no way to determine if there is any difference in unemployment rates.
