Question

Quizplus · Accepted Answer

Susan's observation suggests that the buyers have considered random samples to be representative of the whole, which is an important concept in statistics and sampling. The other answer choices are not applicable to the situation described in the scenario. The study is not necessarily invalid just because the buyers were not informed of the study's purpose, and there is no indication that demand characteristics were present. Additionally, there is no reference to a double-blind observation in the scenario.
