Question

Shingles A research doctor has discovered a new oint-
ment that she believes will be more effective than the

current medication in the treatment of shingles (a painful
skin rash). Eight patients have volunteered to participate

in the initial trials of this ointment. You are the statisti-
cian hired as a consultant to help design a completely

randomized experiment.
a) Describe how you will conduct this experiment.
b) Suppose the eight patients’ last names start with the
letters A to H. Using the random numbers listed below,
show which patients you will assign to each treatment.
Explain your randomization procedure clearly.

c) Can you make this experiment double-blind? How?
d) The initial experiment revealed that males and females

may respond differently to the ointment. Further test-
ing of the drug’s effectiveness is now planned, and

many patients have volunteered. What changes in your
first design, if any, would you make for this second
stage of testing?
