Question

a manufacture claims its cleanser works twice as fast as any orther. Could tests be performed to support the claim

Answer 1

yes if you use that cleanser and another cleanser on the same type of stain you would just time it to see what one works faster and how much faster it works. 

Answer 2

Yes.

Step-by-step explanation:

First of all, a comparison test should be designed that will give the results between the number of cleaners or in two cleaners, which one is best in these.

An experiment should be conducted which is time based task and the performance can be taken of both the cleaners at a time or one after the other. And also notice the efficiency which is more efficient in cleaning.

Therefore, on the basis of timing and efficiency of the experiment, this claim can be supported
