A previous student of this class was curious about the relationship between number of hours a person slept before an exam and the number of correct answers on the exam. She asked a sample of 5 people from her residence hall the number of hours they slept before their first exam and the number of correct answers they got on their first exam. The data are: Number of hours slept Number of correct before exam: X answers on exam: Y XY X2 Y2 8 10 9 7 15. Evaluate the Null Hypothesis (Reject or Fail to reject?). Use the attached table. How did you make your decision? What is your conclusion about the two variables?
