A coffee company wants to bring out a new holiday flavor and decide to conduct a study to see what their customers prefer. In which situation could they use the two-sample t-test for comparing two population means?

They show consumers both options: First peppermint patty iced latte and then dark chocolate and ginger crystal iced latte. They let consumers decide which one they like better and then select the drink that most customers prefer.

They randomly give consumers a sample of both flavors: First peppermint patty iced latte and then dark chocolate and ginger crystal iced latte. After each drink they use an interview to measure happiness with the coffee brand overall. They compare the results to see if the participants feel more or less happy about the brand after trying the second flavor.

They randomly give consumers a sample of either: peppermint patty iced latte or dark chocolate and ginger crystal iced latte. Then they measure to see how many drinks people buy of the sampled flavor.
