2. (12 points) A researcher hypothesizes that watching Comedy Central reduces anger in prison inmates. A sample of 8 inmates is administered the State Anger/Hostility Scale, their mean score is 5.0 with an SD of 2.5. After watching 1 hour of Comedy Central, the State Anger/Hostility scale is readministered. Their mean score is now 3.75, with an SD of 2.33. The inmates' scores (and corresponding z-scores) before and after watching Comedy Central were as follows: Subject Before z-before After z-after 1 8 1.1 8 1.82 2 10 2 7 1.39 3 5 0 4 0.11 4 3 -0.8 2 -0.75 5 4 -0.5 2 -0.75 6 2 -1.2 1 -1.18 7 4 -0.5 3 -0.32 8 4 -0.5 3 -0.32 At a = .05, is the researcher's hypothesis supported? Explain the results in layperson's terms.
