Question

In evaluating the effectiveness of two different brands of laundry detergent (“Super” and “Outstanding”) at three different temperature levels (“cold”, “warm” and “hot”), the amounts of dirt (in µg kg-1) removed in four replicates using each combination are tabulated below. Temperature Detergent Cold Warm Hot “Super” 4, 5, 6, 5 7, 9, 8, 12 10, 12, 11, 9 “Outstanding” 6, 6, 4, 4 13, 15, 12, 12 12, 13, 10, 13 Page 5 of 8 Perform an appropriate test to determine (a) whether the two brands of laundry detergent have significantly different efficiencies, (b) whether temperature has a significant effect on the amount of dirt removed. (c) What is the reproducibility of the test? Explain the meaning of the calculated value.
