Student one claims that his grades this semester are higher than student two. They decide to test the claim.  Student one has 7 classes with an average grade of 89.92 and a standard deviation of 4.6.  Student two has 6 classes with an average of 85.15 and a standard deviation of 6.8.  The variances are NOT the same because there is a different standard deviation.  What can we conclude about this if � = .10? Write the null and alternative hypothesis: What is the original claim in this problem? What is the standardized test statistic that rounds to the nearest 3 decimal places? What is the p-value? What is your decision?
