1.C Scientific Method Scenario

• Smithers thinks that a special juice will increase the productivity of workers at the nuclear power

  plant. 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). Each group consists of workers that are the

  same age and have shown to typically work at the same speed. Group A is given the special

  juice to drink while they work. Group B is not given the special juice. Each group is give an hour

  and after the hour, Smithers counts how many stacks of papers each group has made. Group A

  made 1,587 stacks and Group B made 2,113 stacks.

What is his hypothesis

If you give special juice to workers, then they’ll be more productive
