Firstly, the Shapiro–Wilk Test was used to verify the normality
of the population. The results showed that the populations in both
periods fitted a normal distribution. Afterwards, a contrast on the
variance coefficients (F-Snedecor Test) allowed us to determine
that both samples have the same variances. Finally, after applying
a t-Student test with a 95% confidence level (a = 0.05), the results
showed a statistical value t = 1.5525 and an associate
p = 0.1326, greater than a. It can therefore be assumed that there
are no differences in the generation of MW per working day
between the two teaching periods. Consequently, it can be said
that the daily average per working day is 811.03 kg with a standard
deviation of 96.18 kg and the generation rate is 45.58 g/user/working
day.
