We are told a large nationwide poll recently showed an unemployment rate of 9% in the United States. 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. Let P represent the unemployment rate in her town. Here are the hypotheses she'll use. So her null hypothesis is that, hey, the unemployment rate in her town is the same as for the country. And her alternative hypothesis is that it is not the same.
