Note: aNegative difference between the compared mean values means that the first compared value is less than the second, while the positive difference indicates otherwise; bMean for the first compared value divided the mean for the second value multiplied by 100; cCalculated value of 't' determined using students' t-test; dValue of 't' determined from students' t-test table; S = The difference between the compared means is statistically significant at 0.05 probability level and NS = The difference between the compared means is statistically significant at 0.05 probability level.
