One member of the consumer group in Exercise 15 is concerned that the experiment will take too long and makes some suggestions to shorten it. Comment briefly on each idea.
a) Cut the runs to 8 by testing only the new detergent. Compare the results to results on the standard detergent published by the manufacturer.
b) Cut the runs to 8 by testing only in hot water.
c) Keep the number of runs at 16, but save time by running all the standard detergent runs first to avoid swapping detergents back and forth.
