Do students do better on exams if they mediate for the hour just before the exam? At a large university, the average score on the first exam is 82%. 38 students volunteered to go through an hour of mediation before their first exam. The mediators averaged 84% on the exam with a standard deviation of 5%. Use .05 to test the claim that students do better than 82% on the exams if they mediate for the hour just before the exam.


Given :
n = 38

Original Claim : M > 82
Opposite: M <= 82

THat is all I have figured out ....
 
Did you define a Null Hypothesis? (Usually the status quo.)
