- Can higher-order interactions be dropped to error in the analysis of fractional factorial designs? Why or why not ?Which of the following is correct about Factorial Designs? A. If there are no main effects, there can be no interactions B. Whenever interactions are found, there must be main effects C. Whenever main effects are found, there must be at least one interaction D. When both interactions and main effects are found, the interactions are interpreted firstIn a two factor factorial design with two design factors A and B, why do we generally include the interaction term in the model? What is the major concern if the model ignores the interaction effect?
- to run 2k factorial design in 8 blocks it is necessary to select 3 factors or interactions to form the blocks. as a result there will be a yotal number of effects confounded with blocks equal toSO what would be the L, Lq, and Wq of this problem?

Furthermore, it was found that of the customers who bought a car manufactured by A, 75% would again buy a car manufactured by A, 15% would buy a car manufactured by B, and 10% would buy a car manufactured by C. Of the customers who bought a car manufactured by B, 90% would again buy a car manufactured by B, whereas 5% each would buy cars manufactured by A and C. Finally, of the customers who bought a car manufactured by C, 85% would again buy a car manufactured by C, 5% would buy a car manufactured by A, and 10% would buy a car manufactured by B. Assuming that these sentiments reflect the buying habits of customers in the future, determine the market share that will be held by each manufacturer after the next two model years.

A 1992 study of Dalmatians (by Strain and others, as reported in The Dalmatians Dilemma) found the following: (i) 31% of all Dalmatians have blue eyes. (ii) 38% of all Dalmatians are deaf. (iii) 42% of blue-eyed Dalmatians are deaf. Based on the results of this study is "having blue eyes" independent of "being deaf"? No, since .31 * .38 is not equal to .42. No, since .38 is not equal to .42. No, since .31 is not equal to .42. Yes, since .31 * .38 is not equal to .42. Yes, since .38 is not equal to .42. Submit QuestionQuestion 13
