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.

Super Sneaker Company is evaluating two different materials, A and B, to be used to construct the soles of their new active shoe targeted to city high school students in Canada. While material B costs less than material A, the company suspects that mean wear for material B is greater than mean wear for material A. Two study designs were initially developed to test this suspicion. In both designs, Halifax was chosen as a representative city of the targeted market....

6. To prevent E. coli, meat should be cooked to an internal temperature of at least 160°F. However, different meat patties cooked for the same amount of time will have different final internal temperatures because of variations in the patties and variations in burner temperatures. A regional hamburger chain plans to replace its current burners with one of two new digitally controlled models. If there is a significant difference in the variance of the two models, the chain will select...

An ANOVA test is conducted to compare three different income tax software packages to determine whether there is any difference in the average time it takes to prepare income tax returns using the three different software packages. Ten different individuals' income tax returns are done by each of the three software packages and the time is recorded for each. Because individual tax returns are different the analysis has decided to block on individual returns. The computer results are shown below....
