A detergent company is trying to find a new stain remover ingredient to put in its detergent. Company managers know that baking soda or bleach will be used. They also know that water temperature, cold and warm, affects the stain removal process. An experiment will compare all combinations of these choices. Four types of stains on the same fabric will be subjected to each treatment and scored for stain removal quality.

Answer:

4

Step-by-step explanation:

In this experiment, there will be a total of four experimental units. This is because there will be two options either baking soda or bleach and each one of these will have two experimental units when combined with either cold or warm water. Therefore, we can create the following units as such...

Baking Soda + Cold Water

Baking Soda + Warm Water

Bleach + Cold Water

Bleach + Warm Water

These would be the 4 total experimental units in this experiment.
