A store surveys its target demographic and learns that 86% of people would purchase the product they’ve been heavily advertising. Is this an experiment or an observational study? Can they conclude their current advertising strategy caused the high percentage of interest?

Welcome back. In this problem, we have a store that surveys its target demographic and learns that 86% of people would purchase the product they've been heavily advertising. We wanna know, is this an experiment or an observational study? And can they conclude their current advertising strategy caused the high percentage of interest? As a reminder, in an experiment, we change something. We compare the results of making the change versus not making the change. In an observational study, we just look at things as they are and kind of get a read on the current state of things. In this case, we have a survey that's just asking customers how they currently feel about buying a product. So this is going to be an observational study. As a reminder, in an observational study, we cannot assume causation. So the answer to the second question is no. We can't conclude that the current advertising strategy caused the high percentage of interest. We noticed that there is a high percentage of interest, but we can't say anything about the cause of that interest. Great work.
