Smithers thinks that a special juice will increase the productivity of
workers. He creates two groups of
50 workers each and assigns each
group the same task (in this case,
they're supposed to staple a set of
papers). Group A is given the
special juice to drink while they work. Group B is not
given the special juice. After an hour, Smithers counts
how many stacks of papers each group has made.
Group A made 1,587 stacks, Group B made 2,113
stacks.
