1. Jamie believes that people who watch the news each night do better on a history test (out of 15
points) than people who do not. To test this theory, Jamie asks 7 people to watch the news for an hour
each night before bed for one month, and then administers a history test to these participants (in 2012)
The following year, Jamie asks these same 7 people to avoid watching the news for one month, and the
administers the history test one more time (in 2013). The data follows. Is Jamie right? (13 points)
