In the following situation, a significance test for a population mean µ is called for. State the null hypothesis H0 and the alternative hypothesis Ha in this case. Then, assume p=0.02. State the decision that should be made based upon this p-value. Be sure to justify your decision.

The examinations in a large accounting class are scaled after grading so that the mean score is 50. A self-confident teaching assistant thinks that his students have a higher mean score than the class as a whole. His students this semester can be considered a sample from the population of all students he might teach, so he compares their mean score with 50.
