A consumer products company relies on direct mail marketing pieces as a major component of its advertising campaigns. 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 number of responses to each mailing is given below.
(a) Write the appropriate terms in this model.
(b) Analyze the data from this experiment.
(c) Use the Fisher LSD method to make comparisons among the three designs to determine specifically which designs differ in the mean response rate.
(d) Analyze the residuals from this experiment.

Design Region Number of Responses
1 NE 250
1 NW 350
1 SE 219
1 SW 375
2 NE 400
2 NW 525
2 SE 390
2 SW 580
3 NE 275
3 NW 340
3 SE 200
3 SW 310

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
