1. The problem statement, all variables and given/known data What conclusions can be drawn from this data set? What assumptions are you making? 2. Relevant equations http://i.imgur.com/M9YQGAF.png I hope this is legible. 3. The attempt at a solution The solution is what I'm having trouble with. I just don't get how that test statistic has anything to do with whether that hypothesis is rejected or not, and what meaning it has for the test statistic to be larger than that number.
