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.

Identify the:
1. Independent Variable

is it the special juice

2. Dependent Variable

is it the number of stacks

Write a hypothesis for his experiment:

If Group A workers drink the special juice, then_

is it they will not increase the productivity of work.

  1. Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime.
