  1. Test the claim that the average delay in reaching selected sites on the Internet from Richland is 55 ms. (This one will take some time to collect the data so don't wait too long to get started on this one).
  2. The American League has the designated hitter who gets to bat for the pitcher. Since the pitchers are usually the worst hitters, the on base percentage should be higher for the American League. Use the 2003 season data to test the claim that the American League has a higher on base percentage than the National League.
  3. Use the 2003 season data to test the claim that major league pitchers do better (have a lower earned run average) when they are pitching at home than when they are away.
  4. Demonstrate how the t distribution approaches the normal distribution by making a single graph that has two t distributions (one with df=1 and one with df=5) and a normal distribution on it. Label the distributions as t=1, t=5, and z.
