Once again examine the cube plot for factors A, B and C. What combination of the three factors
produces the second highest value for the life of the product?
A) A = High, B = Low, C = High
B) A = High, B = High, C = Low
C) A = Low, B = Low, C = High
D) A = Low, B = High, C = High
E) A = High, B = Low, C = Low B) A = High, B = High, C = Low
Use the final model equation: 17.47 + 0.41*A + 2.09*B + 1.78*C - 3.03*AC with the factors in
coded units to predict the life of a product unit with the following settings: A=High, B=Low,
C=Low.
A) 20.41
B) 10.97
C) 17.04
D) 20.59
E) 14.34 C) 17.04

A) Every unit in the population is equally likely to be assigned to a given experimental run.
B) An independent estimate of experimental error.
C) An estimate of the measurement error.
D) Account for the variation introduced by controllable noise/nuisance factors. B) An
independent estimate of experimental error.
Which of the following is NOT an advantage of Replication?
, A) An estimate of the measurement error.
B) Greater precision of factorial effect estimates.
C) Increased power for the tests.
D) An independent estimate of experimental error. A) An estimate of the measurement
error.
Which of the following is true of a Resolution IV design?
A) Main effects are aliased with other main effects as well as with some two-factor
interactions.
B) Four-factor interactions are aliased with other four-factor interactions.
C) Two-factor interactions are aliased with three-factor interactions but main effects are free
of aliasing.
D) None of the effects is aliased with another.
E) Main effects are aliased with three-factor interactions and two-factor interactions are
aliased with other two-factor interactions. E) Main effects are aliased with three-factor
interactions and two-factor interactions are aliased with other two-factor interactions.
Which of the following is true of a Resolution III design?
A) Main effects are aliased with two-factor interactions and two-factor interactions with each
other.
B) Two-factor interactions are aliased with three-factor interactions but main effects are free
of aliasing.
C) None of the effects is aliased with another.
D) Main effects are aliased with three-factor interactions.
E) Three factor interactions are aliased with each other. A) Main effects are aliased with
two-factor interactions and two-factor interactions with each other.
