**MathGuru**, Friday, March 27, 2009 at 9:34amHere's a few hints:

1. Set up a null and alternative hypothesis based on the information given.

2. The test will be a one-sample z-test (the number of homeruns is normally distributed). You will need to find mean and standard deviation of the data.

3. The p-value is the actual level of the test statistic (found using a z-table).

4. Use appropriate confidence formulas

for the data. (You will have to check a z-table again to determine z for each interval.)

I hope this will give you some clues on how to get started on this one.
