The results provided in Figure 16 and 17 are tested by using Pearson's chi square significance 
tests. A strong deviation between the observed and the expected number of valuations is 
indicative of a close relationship between the tested attributes  efficiency  and  IT usage  in the 
cross classified table. For the operational focus, the hypothesis that there is no significant 
correlation between the efficient usage of IT and the strategic orientation to reduce costs can be
