1. The USA Today and Major League Baseball websites regularly report information on individual player salaries. Go to one of these sites and find the individual salaries for your favorite team. Compute the mean and the standard deviation. Is it reasonable to conclude that the mean salary on your favorite team is different from $2.0 million? If you are more of a football, basketball, or hockey enthusiast, information is also available on their salaries.
2. The Gallup Organization in Princeton, New Jersey, is one of the best-known polling organizations in the United States. They often combine with USA Today or CNN to conduct polls of current interest. They also maintain a website at http://www.gallup.com. Consult this website to find the most recent polling results on Presidential approval ratings. You may need to click on Fast Facts. Test whether the majority (more than 50 percent) approve of the President's performance. If the article does not report the number of respondents included in the survey, assume that it is 1,000, a number that is typically used. |
