Amanufacturer claims its cleanser works twice as fast as any other. could test be performed to support the claim? explain

Yes, a test could be performed to support the claim.

Hypothesis: The claim that a manufacturer’s cleanser works twice as fast as any other cleanser.

So, based from this hypothesis, we can perform the following tests:

We assign Cleanser A to the manufacturer that claims that their cleanser works twice as fast as any other cleanser and Cleanser B to the cleanser to be compared with.

1.       Get two tiles and put the same amount of stain on them.

2.       Apply Cleanser A on the first tile and Cleanser B on the second tile.

3.       Apply the same amount of force in removing the stains on both tiles

4.       Record the amount of time it takes to remove the stains on each tile.
