Well 6^2 is 36 so my best estimate is 6
        
                    
             
        
        
        
A total of 
  108*19 = 2052 
pages will be printed. We suppose paper will be purchased in reams of 500 pages each, so
  ceiling(2052/500) = ceiling(4.104) = 5 
reams will be needed. The the cost will be
  (5 reams)*($3.69/ream) = $18.45
The paper for the reports will cost $18.45.
        
             
        
        
        
At the standard 0.05 value, this is not significant, however at a 0.01 level, it would be significant
