Another interesting characteristic is the number of different models used by the packaging/bottling firm, as well as their specificity. To analyze the differences between the two countries with respect to these two variables, two independent sample t tests were carried out. No significant differences can be appreciated in the number of models used (t = 1.000, significance level = 0.314) or in their specificity (t = 1.257, significance level = 0.210) between the two countries.
