Question
(9.10) What are the effects of repeated exposure to an advertising message? The answer may depend on both the length of the ad and how often it is repeated. An experiment investigated this question using undergraduate students as subjects. All subjects viewed a 40-minute television program that included ads for a digital camera. Some subjects saw a 30-second commercial; others, a 90-second version. The same commercial was shown either one, three, or five times during the program.
This experiment has two factors: length of the commercial, with two values, and repetitions, with three values. The six combinations of one value of each factor form six treatments. The figure below shows the layout of the treatments. After viewing, all the subjects answered questions about their recall of the ad, their attitude toward the camera, and their intention to purchase it. These are the response variables.
Which of the following outlines, is an appropriate design of the experiment?

Please Tell me what design and where Brower will be assigned. PLEASE SHOW WORK!!!!
Step 1:Which of the following outlines, is an appropriate design of the experiment?
Design 2. Design 4. Design 3. Design 1.Step 2:
Use Table B, starting at line 135 to randomly assign the subjects to the treatments. Which group will Brower be assigned to? Brower will be assigned to the first group. Brower will be assigned to the third group. Brower will be assigned to the forth group. Brower will be assigned to the second group.
Explanation / Answer
Answer to the question)
The perfect design is design four.
Reason:
There are total sixe groups based on the two factors. In this case we need to compare the outcomes of all the six treatments and need to see the interaction effect as well. That is the reason why the design four that expresses the six groups is the correct design for this scenario.
