My group has been arguing over this question...

Some are getting 0.299 for the p-value, personally I'm getting 0.298.

If someone could explain which is the correct answer, and how would it be calculated, it would be much appreciated, thanks .Bill claims that, on average, books are more expensive to buy for the Kindle eBook reader than the Kobi eBook reader. She randomly sampled 50 books sold for the Kindle, and got a sample mean = $31, and s = $26. Then she randomly sampled 45 books sold for the Kobi, and got a sample mean = $28, and s = $29.

If you conduct a hypothesis test with respect to Bill’s claim (0.05 significance level), what is the p-value that you obtain? (Use Case I)
