![Question2: A consumer products company relies on direct mail
marketing pieces as a major component of its advertising cam-
paigns. The company has three different designs for a new
brochure and wants to evaluate their effectiveness, as there
are substantial differences in costs between the three designs.
The company decides to test the three designs by mailing 5000
samples of each to potential customers in four different regions
of the country. Since there are known regional differences in
the customer base, regions are considered as blocks. The num-
ber of responses to each mailing is as follows.

(a) Analyze the data from this experiment.
(b) Use the Fisher LSD method to make comparisons
among the three designs to determine specifically
which designs differ in the mean response rate.
(c) Analyze the residuals from this experiment.
