Question Four An experiment was conducted to evaluate the effect of different detergents and water temperatures on the cleanliness of ceramic substrates. The experimenter selected three different detergents based on their pH levels, and conducted a series of experiments at four different water temperatures. Cleanliness was quantified by measuring the contamination. The coded data are shown in the below Table Water Detergent Detergent A Detergent B Detergent C D Cold 15 18 10 Cool 12 14 9 Warm 10 18 7 Hot 6 12 5 Analyze these data to show that if there are any differences between the different detergents and the different water temperatures (a = 0.01)
