Researchers investigated how the size of a drinking glass affects how much soda people tend to pour themselves. People were randomly given either a 17 oz or a 25 oz​ glass, and were invited to pour as much soda as they liked. Did the glass size change the selected portion​ size? The summaries are shown to the right. Assume any assumptions and conditions are satisfied.
