You are running a simple study to determine if time of day affects student test performance. One
  group takes a test at 9 AM, the other group takes the same test at 6 PM.

  session, the group seems distracted by the school band, which is practicing nearby, but the
  students finish the test on-time with no apparent problems. When you analyze the results, you
  find the morning group performed significantly better than the evening group. What should you
