Mrs. Hutchins-Trapp wants to see which detergent cleans clothes the best. She gets 4 white t-shirts from the store and
places 5 ml of spaghetti sauce in the middle of each t-shirt. She allows the t-shirts to dry for 24 hours. She goes to the
laundromat and places each t-shirt in a separate washing machine. She sets each washing machine to Normal cycle. In each
washing machine, she puts one of the following: Tide, Target brand and Cheer. In the fourth machine, she doesn‛t put any
detergent.
2. Which of the following would be the problem for this experiment?
A. It will be wasteful to use that much water to wash just one t-shirt.
B. If t-shirts with spaghetti stains are washed using Tide, Target brand, and Cheer
detergents, then the Cheer detergent will remove the most stain.
C. 5 ml of spaghetti sauce is placed in the middle of each t-shirt.
D. Will the brand of detergent affect the amount of stain that is left on the shirt?
3. Which of the following would be the best hypothesis for this experiment?
A. If t-shirts with spaghetti stains are washed using Tide, Target brand, and Cheer
detergents, then the Cheer detergent will remove the most stain.
B. If different detergents are used to remove spaghetti stains, then one will do better than
the others.
C. Will all laundry detergents perform the same?
D. Will the Target brand detergent perform worse than the Tide and Cheer detergent?
4. Which statement describes the results shown in the graph?
A. The t-shirts washed without detergent were
significantly cleaner than those washed with
detergent.
B. The t-shirts washed with Tide were significantly
cleaner than those washed without detergent.
C. There is an insignificant difference between all the
tests.
D. The results are inconclusive.
