Answer 1

Here, the researcher is interested in how consumers make purchase decisions for a specific type of product. The researcher want to know whether price or quality matters more to the consumer. So, the same set of consumers give ratings on both price and quality and then the average rating is compared to see which of the two matters more. Therefore, since the same set of consumers give ratings on both price and quality , the sample are dependent , or paired here. Hence, we use the Paired sample t-test here.

Answer : Paired sample t-test.
