A paired samples t-test would be the best choice because it allows for the comparison of the same group of individuals before and after an intervention. This test would determine if there is a significant difference in productivity before and after the training class. The independent samples t-test would be used to compare the means of two unrelated groups, which is not applicable in this scenario. ANOVA and F-test are used to compare the means of more than two groups, which is not necessary in this case because we are only interested in the productivity of one group before and after the intervention.
