  1. Groups with the same letters are not statistical different (chi-square test letter A: chi-square = 2.089, df = 2, p = 0.352; chi-square test letter B: chi-square = 3.241, df = 2, p = 0.198). Chi-square test on all groups shows statistically significant difference (chi-square = 20.074, df = 5, p = 0.01).
