Researchers are interested in whether people prefer the taste of sugar or saccharin. To conduct their research, they first use sugar to bake a cake, and then use saccharin to bake brownies. Once fully cooked, they bring the cake and brownies to a local supermarket and set up a tasting station. As people walk by, the researchers ask them to taste the two items and choose which one they prefer. The researchers find a statistically significant effect such that people prefer the saccharin-filled brownies over the sugar-filled cake. What can be concluded from the study? Group of answer choices
