In Exercises 33–36, identify which of these designs is most appropriate for the given experiment: completely randomized design, randomized block design, or matched pairs design.
Lipitor A clinical trial of Lipitor treatments is being planned to determine whether its effects on diastolic blood pressure are different for men and women.
The effect of three different grades of gasoline on fuel economy in car engines is
being studied. Fuel economy is measured using brake-specific fuel consumption after the
engine has been running for 15 minutes. Five different car engines are available for the study,
and the experimenters conduct the following randomized complete block design.
Car
Gasoline grade

3
0.523 0.605 0.498 0.410 0.520
(a) Analyze the data from this experiment.
(b)Use the Bonferroni correction method to make comparisons among the three grades of
gasoline to determine specifically which grades differ in brake-specific fuel consumption.
Describe the difference between a completely randomized design, a randomized block design, and a factorial experiment, and describe a situation in which each type of experiment would be utilized.
