Answer:
The answer to the question: What type of study is being conducted when Lad´s End Home mails a catalog with a fluffy set of towels on the cover to one group of consumers and the same catalog with a cover graphic of a beautifully-made bed to another consumer group to test differences between the two groups, would be: Experimental study.
Explanation:
The reason for this being the answer comes from the purpose that the researchers have given to the study itself. By sending the same catalog to two groups, each catalogue with a specific set of characteristics, to measure their responses to them and contrast the responses, these researchers are experimenting and seeking the results of that experimentation. This is why the answer is experimental, and not any of the other types of study types.
