A researcher is interested in the effects of sleep deprivation and caffeine intake on mood. Participants were randomly assigned to a sleep condition (normal or deprived) and a caffeine condition (0 cups, 2 cups, or 4 cups). After the manipulations, mood was measured (such that higher numbers indicated better mood). The results were as follows:

      Normal Condition          Deprived Condition
   0 cups   2 cups   4 cups         0 cups   2 cups   4 cups
       16      18       18             0       5       6
       17      20       17             6       4       8
       20      20       17             3       4       6
       19      19       17             2       2       7
       18      18       16             4       5       8

Analyze these data using a factorial analysis of variance and including R2 for each effect.
