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.

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. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.

Identify the:
1. Independent Variable
coco juice
2. Dependent Variable
slime removed or is it how the slime looks
Write a hypothesis for his experiment:
If coconut juice and water is sprayed on the slime, then

is it : that it has no effect

For Juice, Ho: no difference in stacks

for slime, Ho: no difference between effects of juice vs. water

i don't understand is that the hypothesis

1. Independent Variable: The independent variable in this experiment is the special juice. It is the variable that is manipulated by Smithers, as he gives it to Group A but not to Group B.

2. Dependent Variable: The dependent variable is the number of stacks of papers made by each group. It is the variable that is measured and is expected to be influenced by the independent variable, which is the special juice.

Hypothesis: If Group A workers drink the special juice, then their productivity of work will increase.

It should be noted that the provided hypothesis suggests a different outcome compared to the actual results described in the question. The hypothesis assumes an increase in productivity, while the actual results show that Group B, without the special juice, made more stacks of papers than Group A, who consumed the special juice.
