Exercise 12-48 (Algo) (LO12-5) Robert Altoff is vice president of engineering for a manufacturer of household washing machines. As part of a new product development project, he wishes to determine the optimal length of time for the washing cycle. Included in the project is a study of the relationship between the detergent used (four brands) and the length of the washing cycle (18, 20, 22, or 24 minutes). In order to run the experiment, 32 standard household laundry loads (having equal amounts of dirt and the same total weights) are randomly assigned to the 16 detergent-washing cycle combinations. The results (in pounds of dirt removed) are shown here: Detergent Cycle Time (min) 24 Brand 18 20 22 A 0.14 0.14 0.14 0.15 0.13 0.14 0.14 0.13 B 0.14 0.16 0.16 0.15 0.16 0.15 C 0.17 0.17 0.15 0.18 0.17 0.14 0.17 0.18 0.18 0.16 D 0.14 0.13 0.14 0.13 0.13 0.13 0.14 0.13 pictureClick here for the Excel Data File Required: a. Complete an ANOVA table. Use the 0.05 significance level. (Do not round your intermediate calculations. Enter your SS, MS, p- value to 3 decimal places, F to 2 decimal places, and F crit to 4 decimal places.) Source of Variation Cycle Time Brand Interaction Within Total b. Choose the right option. SS df MS F p-value F crit the null of no interaction between cycle time and detergent brand. the null of no difference in means for the different cycle times. the null of no difference in means for the different detergent brands.
